- updated to 1.999813 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 1.999813 2018-04-18 * Fix CPAN RT #125108. Remove test files try.pl, t/author-bpi-big-mbf.t, and t/release-unused-vars.t, which were included in the 1.999812 distribution by accident.

- updated to 1.999812 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES

- updated to 1.999811 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2017-03-15 v1.999811 pjacklam * Fix an old in the Math::BigFloat methods as_hex(), as_oct(), and as_bin() methods resulting in loss of accuracy. This bug was introduced in bug in Math-BigInt-1.76. Due to a naive copy and paste by me, and lack of tests, this bug was also present in the newer to_hex(), to_oct(), and to_bin() methods. This shows the bug, as it did not print "0xffff...": print Math::BigFloat -> from_hex("f" x 30) -> as_hex(); * Fix incorrect formatting in the output from the Math::BigFloat methods to_hex(), to_oct(), and to_bin() when the output was zero. A prefix was added when it shouldn't have been. * Add tests to bigintpm.inc and bigfltpm.inc for better testing of as_hex(), as_oct(), and as_bin() as well as to_hex(), to_oct(), and to_bin(). * "Synchronize" tests and code formatting in bigintpm.inc and bigfltpm.inc.

- updated to 1.999810 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2017-03-01 v1.999810 pjacklam * CPAN RT #120240 revealed that the problems with undefined values is still present. After a close examination, I believe the only way to get this really working is to to make blog() call objectify() differently depending on whether the base for the logarithm is undefined or not. That way we can avoid objectify() converting the undefined value to a zero. Ideally, we should warn about undefined values when used in any other context, but we'll handle that in a later release. See also the related changelog entry for v1.999801. * Fix the way the argument count is computed in objectify(). When an argument count of 0 is given, it means that we should objectify all input arguments. However, it turned out that the actual argument count was computed incorrectly. * Fix CPAN RT #120242 rearding c3 method resolution.

- updated to 1.999809 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2017-02-10 v1.999809 pjacklam * When a new method is added to Math::BigInt or Math::BigFloat, and this new method requires a new backend library method, die with a suitable error message if the installed backend library does not support this new method. The error message says that the method requires a newer version of the backend library. * Fix typos in Math::BigFloat and Math::BigInt. * Add bfib() and blucas() to Math::BigInt. They return Fibonacci and Lucas numbers, respectively. The actual computation of the numbers is done by the backend library. Documented both methods in POD. Add test files bfib-mbi.t and blucas-mbi.t. * Add _fib() and _lucas() to Math::BigInt::Lib. They return Fibonacci and Lucas numbers, respectively. Document both methods in POD. Add test files author-lib-arithmetic-unary-_fib.t and author-lib-arithmetic-unary-_lucas.t.

- updated to 1.999808 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2017-01-11 v1.999808 pjacklam * In Math::BigInt and Math::BigFloat, add methods bdfac() for double factorial. Add tests for this method. * In Math::BigInt and Math::BigFloat, add methods to_hex(), to_oct(), and to_bin() for hexadecimal, octal, and binary string output without prefix. Even for Math::BigFloat there is still only support for integer output. Add tests for these methods. * Add test for as_oct() corresponding to the old tests for as_hex() and as_bin(). * In Math::BigInt::Lib, add method _dfac() for double factorial. Add corresponding tests. * In Math::BigInt::Lib, fix bug in overloaded "int". * In Math::BigInt::Lib, implement much faster versions of _from_hex(), _from_oct(), and _from_bin(). * In Makefile.PL, improve the wording in the message displayed if some of the installed backend libraries are not a subclass of Math::BigInt::Lib (and hence will not provide * Fix minor bugs in some of the author library test files (t/author-lib*.t). * Allow leading and trailing whitespace in the input to from_hex(), from_oct(), and from_bin(). Add tests to verify. This is a regressions (CPAN RT #119805).

- updated to 1.999807 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-12-23 v1.999807 pjacklam * Add a message to Makefile.PL recommending upgrade if old libraries are installed. This message is more or less equivalent to the one appearing in Math-BigInt up until v1.997. * Improve the documentation (POD) in Math::BigInt::Lib. * Speed up _sqrt() and _root() in Math::BigInt::Lib. * Remove checking for exception cases (cases that would return +Inf, -Inf, or NaN) in Math::BigInt::Lib. It has been documented for a long time that such checking should be done by the caller. * Add library methods _to_bin(), _to_oct(), _to_hex(), which are equivalent to the _as_bin(), _as_oct(), and _as_hex() methods respectively, except that the _to_*() methods don't use a prefix in the output. This removes the need for the frequent removal of the various prefixes. Now each _as_*() method calls the equivalent _to_*() method, adds a prefix, and returns the output. The _to_*() methods are faster than the equivalent _as_*() methods were. * Add author test files for the methods _to_bin(), _to_oct(), and _to_hex(). * Add library method _to_bytes(). The method _as_bytes() would have been called _to_bytes() if I had thought of it earlier. The method _as_bytes() is now just an alias to _to_bytes(). The _to_bytes() method also fixes a bug that was present in the _as_bytes() method. (CPAN RT #119346). * Add author test files for the method _to_bytes(). * Add more tests for library methods _inc() and _dec(). When trying to bring the Math::BigInt::BitVect library back to life I realized that the test suite didn't catch certain errors in _inc() and _dec(). * Die if trying to use as_bytes() or from_bytes() with a backend library that doesn't support the corresponding library methods. * Correct minor errors in the output messages in the test files. * Improve/correct various comments in the source code. * More diagnostic output is displayed by the author test files if the AUTHOR_DEBUGGING environment variable is set.

- updated to 1.999806 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-12-13 v1.999806 pjacklam * Add more logic to Makefile.PL regarding INSTALLDIRS (CPAN RT #119199 and #119225). * In the TODO file, remove stuff that has been implemented.

- updated to 1.999805 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-12-11 v1.999805 pjacklam * Fix Makefile.PL so that this module installs over the core version. * Add more tests for _nok() (binomial coefficient "n over k"). These new tests revealed some problems with some of the backend libraries when _nok() was given very large arguments. * Remove t/Math/BigFloat/#Subclass.pm#, which is an Emacs temporary file included by accident.

- updated to 1.999804 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-12-07 v1.999804 pjacklam * Implement as_bytes(), as requested (CPAN RT 119096). Also implement the inverse conversion from_bytes(). This applies to Math::BigInt only. (Alas, these methods will be inherited from Math::BigInt into Math::BigFloat, Math::BigRat etc. where the methods won't work. Fixing this class relationship is an issue of its own.) * Implement _as_bytes() and _from_bytes() in Math::BigInt::Lib. Preferably, the various backend libraries will implement faster versions of their own. Add author test files for testing these methods thorougly. * Fix from_hex(), from_oct(), and from_bin(). - When called as instance methods, the new value should be assigned to the invocand unless the invocand is read-only (a constant). - When called as instance methods, the assigned value was incorrect, if the invocand was inf or NaN. - Add tests to t/from_hex-mbf.t, t/from_oct-mbf.t, and t/from_bin-mbf.t to confirm the fix. - Add new test files t/from_hex-mbi.t, t/from_oct-mbi.t, and t/from_bin-mbi.t for better testing of these methods with Math::BigInt. * Correct typo in Math/BigInt/Lib.pm (otherise -> otherwise) (CPAN RT 118829). * Add POD coverage testing of Math::BigInt::Lib to t/03podcov.t.

- updated to 1.999803 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES

- updated to 1.999802 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-11-28 v1.999802 pjacklam * When bzero(), bone(), binf(), and bnan() are used as constructors, don't check whether the class allows the object to be modified. This applies to both Math::BigInt and Math::BigFloat. * Improve bgcd() and blcm(). This applies to both Math::BigInt and Math::BigFloat.

- updated to 1.999801 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES

- updated to 1.999800 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-11-15 v1.999800 pjacklam * Upgrade bundled Module::Install from version 1.16 to version 1.17. * Add Math::BigInt::Lib (lib/Math/BigInt/Lib.pm), a parent class for Math::BigInt backend libraries. * Use objects in Math::BigInt::Calc, not just array refs. Also use OO-style, i.e., use $class->_add($x, $y) rather than _add($class, $x, $y). * Not all library methods modify the invocand, so call library methods as, e.g, $x = $LIB->method($x, $y) rather than just $LIB->method($x, $y). * Math::BigInt::Calc is now a subclass of Math::BigInt::Lib. * Add Math::BigInt::Lib::Minimal (t/Math/BigInt/Lib/Minimal.pm) for testing inheritance from Math::BigInt::Lib. * Minor simplification in Math::BigInt::Calc->_str(). * Speed up Math::BigInt::Calc->_root(). * Remove test files that were included in the previous release by accident. * Add more tests and use more verbose output in some tests. * Fix typo in lib/Math/BigFloat.pm * Fix documentation error in lib/Math/Calc.pm * Use Config::Tiny and an .ini file to handle the library specific configuration for the author-lib*.t test files.

- updated to 1.999727 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-11-04 v1.999727 pjacklam * Skip test exceeding the range of VAX floating point number in t/bigintpm.inc (CPAN RT 118468). * Fix typo in lib/Math/BigInt.pm (CPAN RT 118550).

- updated to 1.999726 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-07-15 v1.999726 pjacklam * Re-insert Math::BigFloat->DESTROY, which was accidentally removed in v1.999725.

- updated to 1.999725 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-07-13 v1.999725 pjacklam Changes: * Add method is_finite(). * In Math::BigInt and Math::BigFloat, remove warnings about deprecated usage, at least until we have removed this usage from the "bignum" distribution. These warnings were too annoying for some people. Improvements: * Faster bnok() when the library (backend) does not support it. * In the Math::BigFloat method bpi(), use a precomputed list of digits when the accuracy is <= 1000. This speeds up the trigonometric functions considerably, when I will introduce range reduction in a later release. This makes the _atan_inv() method redundant, so remove it. Also, the _alen() library method is now only used in _log_int(), which is good, because it isn't clear from the docs and tests what it was supposed to do. Fixes: * Fix bug in the Math::BigInt::Calc library method _digit(). It would sometimes return undef or an empty string when it should have returned zero. * Fix bug in the Math::BigInt::Calc library method _rsft(). It would sometimes return two output arguments. * Fix bug in the Math::BigInt::Calc library method _lsft(). When the number zero was shifted N places in base 10, the result was not zero, but an invalid object. * Fix bug in the Math::BigInt::Calc library methods _and(), _or(), and _xor(). They always assigned zero to the first input argument (the invocand). * Improve the Math::BigInt::Calc library method _log_int() for the cases when the output is zero or one. Also simplify the code. * Simplify the code for the Math::BigInt::Calc library method _zeros(). * Reformat Math::BigInt::Calc so it is easier to read, for me anyway. * Add file t/author-bnok-mbi.t * Add one test file for every method in the libraries, including t/Math/BigInt/Lib/TestUtil.pm with test utilities. * Clean up whitespace in all files in the distribution. * Better testing in t/author-bpi-mbf.t * The Math::BigInt::Calc library now always uses integers inside the objects, so there is no longer any need for all the "0 + ..." to convert strings to numbers, and the "int()" inside "length(int(...))" to determine the length of an array element. The only case that needs "0 + ..." now is the constructor _new(), whose input is a string. Note, however, that the Math::BigInt::FastCalc library method _new() still creates objects with leading zeros, so until that is fixed, we can't remove all the "0 + ..." etc. until Math::BigInt::FastCalc has been modified.

- updated to 1.999724 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES

- updated to 1.999723 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-06-09 v1.999723 pjacklam * Add Math::BigInt and Math::BigFloat methods bnstr(), bestr(), and bdstr(), as well as corresponding methods nparts(), eparts(), and dparts(). Also add test files bdstr-mbf.t, bdstr-mbi.t, bestr-mbf.t, bestr-mbi.t, bnstr-mbf.t, bnstr-mbi.t, bsstr-mbf.t, bsstr-mbi.t, dparts-mbf.t, dparts-mbi.t, eparts-mbf.t, eparts-mbi.t, nparts-mbf.t, nparts-mbi.t, sparts-mbf.t, and sparts-mbi.t. * Fix documentation errors.

- updated to 1.999722 see /usr/share/doc/packages/perl-Math-BigInt/CHANGES 2016-04-16 v1.999717 pjacklam * Using new() with an undefined argument no longer gives a warning. Explicit use of this is discouraged, but it is sometimes used by the modules themselves issuing warnings that is confusing to the end user. Just uncomment the code, since we plan to reintroduce this warning later. * Avoid using L<> around e-mail addressess in POD. 2016-04-22 v1.999718 pjacklam * Improve documentation on large, unquoted input values to Math::BigInt. * Remove stuff from bitfltpm.inc that was placed into author-numify-mbf.t, but accidentally still present in bitfltpm.inc. Adjusted test counts as needed. * Fix file headers in author-bmod-bdiv-mbi.t and author-btmod-btdiv-mbi.t. * Add bnan(), binf(), and bsub() methods to Math::BigFloat. This is a step along the way to having Math::BigFloat no longer being a subclass of Math::BigInt. * Using bnan, binf(), bzero() and bone() as functions is deprecated. This is a step along the way to a pure object oriented design. * When bnan() and binf() are used as instance methods, they no longer delete the accuracy and precision instance variables. * Add test files from_bin-mbf.t, from_oct-mbf.t, and new-mbf.t. * Remove some code for Perl prior to 5.6. Such old versions are no longer support anyway. * Fix buggy handling of NaN in bcmp(). * Add methods beq(), bne(), blt(), ble(), bgt(), and bge() to Math::BigInt and Math::BigFloat. These methods are called for the overloaded operators. * Add overloading of '==', '!=', '<', '<=', '>', to to Math::BigInt and Math::BigFloat and fix the broken overloading of '>='. These overloaded operators now behave like the equivalent core Perl operators. * Add test file author-relop-mbi-mbf.t for testing bcmp(), beq(), bne(), blt(), ble(), bgt(), and bge(), as well as the overloaded operators '==', '!=', '<', '<=', '>', and '>='. * 'int' now truncates a Math::BigFloat object to an integer without converting it to a Math::BigInt. When an object becomes a Math::BigInt, further computations with that object as invocand causes the arguments to be converted to Math::BigInt objects too, leading to unexpected results. This is confusing people. Unless downgrading is in effect, no Math::BigFloat object should become a Math::BigInt unless a Math::BigInt is explicitly requested. * For Math::BigFloat, modify bitwise operations brsft() and brsft(), and add band(), bior(), bxor(), and bnot(). These now handle floating point numbers the same way as core Perl does, i.e., truncate non-integers to integers before applying the bitwise operator. This change will also make Perl's behaviour more consistent whether 'use bignum' is in effect or not. * Add overloading of '~' (bitwise not). It just calls bnot(), which has been implemented for ages. * Fix error in POD for bone(). * Take parts of the code in t/calling.t and move it into the new files t/calling-class-methods.t and t/calling-instance-methods.t. * Improve test descriptions in t/mbimbf.inc. 2016-04-25 v1.999719 pjacklam * Revert the change to Math::BigFloat's blsft() and brsft() methods, which truncated the input (and output) to integers. However, now convert the base to an object only when the base isn't an object already. Also return NaN if any of the three operands is a NaN. * Change t/bigfltpm.inc to reflect the changes to blsft() and brsft(). Also, when a method should be tested, actually test that method, not the overloaded operator, which doesn't necessarily behave in the exact same manner as the method. This applies to the methods binc(), bdec(), bpow(), badd(), bsub(), bmul(), bdiv() in scalar context, brsft(), blsft(), and bmod(). * The first output argument from objectify() is the class name, so use the variable name $class, not $self. 2016-04-26 v1.999720 pjacklam * Overloaded 'int' should not modify it's argument. * Better documentation of blsft() and brsft(). 2016-04-26 v1.999721 pjacklam * Prevent Math::BigFloat methods band(), bior(), bxor(), and bnot() from modifying unmodifiable objects. 2016-04-26 v1.999722 pjacklam * Fix bug in bone() and binf() when used as a function. The error caused warnings about using an unitialized variable. This fix applies to both Math::BigInt and Math::BigFloat.
