Sync Math::BigInt with CPAN 1.999837
From ChangeLog:
1.999837 2022-07-02
* Improve the interoperability between objects of different classes for
* the
methods that are still used as functions.
1.999836 2022-06-24
* Improve compatibility with older versions of the Math-BigRat
* distribution.
Math-BigInt version 1.999835 works with Math-BigRat version 0.2623
and newer.
Math-BigInt version 1.999836 works with Math-BigRat version 0.2618
and newer.
* Re-enable upgrading in Math::BigFloat->bdiv().
* Fix an error in the enabling/disabling of upgrading/downgrading.
* Fix typos and other formatting errors.
1.999835 2022-05-24
* Fix bug related to upgrading in Math::BigInt->brsft(). This bug
only showed up in Perl versions 5.16 and older.
1.999834 2022-05-23
* Further improvements to upgrading and downgrading.
1.999833 2022-05-23
* Fix Math::BigFloat->bpi(). The previous attempt at correcting it
wasn't sufficient. Added test to verify the fix.
* Correct the formatting in the CHANGES file.
1.999832 2022-05-21
* Improve as_int(), as_float(), and as_rat() so that they return a
Math::BigInt, Math::BigFloat, and Math::BigRat, respectivly,
regardless of upgrading and downgrading.
* Improve stringification method bsstr() so that it handles upgrading
and downgrading better.
* Fix Math::BigFloat->bpi(), which unfortunately didn't handle
downgrading.
* Avoid unnecessary downgrading/upgrading.
* Add missed cases where downgrading/upgrading should be performed.
* Avoid unnecessary stringification.
1.999831 2022-05-16
* Further improvements to upgrading, downgrading, and rounding.
* New stringification method bfstr() for representing numbers as
* fractions.
E.g., Math::BigFloat -> new("1.25") -> bfstr() returns "5/4".
* Miscellaneous bug fixes.
* Fixed errors and typos in the documentation.
