2.005003 2025-04-13
* Add new methods to_fp80() and from_fp80() for encoding and decoding values in
the x86 extended-precision 80 bit format.
2.005002 2025-03-28
* Fix the handling of read-only objects in bblsft() and bbrsft() in
Math::BigFloat and Math::BigRat.
2.005001 2025-03-25
New:
* Add new method bperm() to Math::BigInt, Math::BigFloat, and Math::BigRat.
* Add the following methods to Math::BigRat and Math::BigFloat:
bilog2(), bilog10(), bclog2(), bclog10(), bfib(), blucas(),
from_bytes(), from_base(), to_bytes(), to_ieee754()
* Add method bmuladd(), bgcd(), and blcm() to Math::BigRat.
* Add method bpi() to Math::BigRat. It returns a rational approximation of PI
accurate to the specified accuracy or precision, or the default accuracy if
no accuracy is specified.
* Add methods bdstr(), bnstr(), and bestr() to Math::BigRat.
* Add support for rounding in Math::BigFloat methods bdstr(), bestr(), bnstr(),
and bestr().
* Add method from_ieee754() to Math::BigInt and Math::BigRat, including
documentation. In Math::BigInt, from_ieee754() is similar to the other
from_xxx() methods in that way that it returns a NaN if the input is a finite
non-integer.
* Add new backend library method _scmp() for doing signed comparison.
Changes/Improvements:
* Method new() now always returns a new object, as would be expected.
* Make bgcd() in Math::BigRat and Math::BigFloat support non-integer arguments.
Now, bgcd(0.8, 1.2) in Math::BigFloat returns 0.4, and bgcd(4/5, 6/5) in
Math::BigRat returns 2/5.
* Make blcm(0, 0) work the same way in Math::BigInt, Math::BigRat, and
Math::BigFloat. Now blcm(0, 0) is always 0.
* Correct the documentation for is_inf(), bceil() and bfloor()
* Methods bdiv() and bmod() are now aliases to bfdiv() and bfmod(),
respectively. (This doesn't change the behaviour of bdiv() and bmod().)
* Math::BigFloat methods bfmod() and btmod() are faster than before.
* Improve documentation for bnok().
* Improve upgrading and downgrading, e.g., use $class->upgrade() rather than
just $upgrade, since the former works better for sublasses.
Fixes:
* Add missing calls to modify().
* All boolean methods now return 1 or 0. Some would return 1 or "".
* Harmonise methods in different classes so they behave similarly, at least to
the extent possible.
* Fix bug in Math::BigInt->bfib() causing sign to be incorrect for some of the
output values when bfib() was called in list context with a negative input.
* Correct miscellaneous typos and errors in the documentation.
2.004001 2025-02-12
* Improve upgrading and downgrading.
- Upgrading and downgrading is more consistent.
- Upgrading and downgrading now keeps the reference, so in the following
example, $x changes from being a Math::BigInt with a value of 2 to a
Math::BigFloat with the value 1.4142...
perl -Mbignum -le '$x = 2; $x -> bsqrt(); print $x'
* Fix bug in Math::BigFloat->bdiv(): in list context, bdiv() would do floored
division, except when the denominator was 1. Now, bdiv() always does floored
division.
