Math-BigInt 1.999807

on Perl CPAN

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.
