Math-BigInt 1.999701

on Perl CPAN

The POD documentation, as well as the comments in the code, said that
$x->bdiv($y) in list context should return quotient $q and remainder $r so
that $x = $q * $y + $r, and that the remainder (modulo) $r should correspond
to Perl's % operator as well as the bmod() method. This has not been the
actual behaviour. This is now fixed. In scalar context, only the quotient is
returned.

Clearer POD documentation for the bdiv() and bmod() methods.

All non-integer input values to Math::BigInt gave a NaN, except non-zero
numbers in the range (-1,1) that were written without an exponent, e.g.,
"-0.75" and "0.5". Now also these return a NaN.

Input values with a large (absolute value) negative exponent, e.g.,
1e-9999999, now return NaN. The former behaviour was to die with the message
"Quantifier in {,} bigger than 32766 in regex; marked by ..."

Intermediate computations in blog() increased the number of digits
significantly in some cases. Now reduce the number of digits by rounding.
However, keep some extra digits for remaining intermediate computations
before the final rounding.

When $x is a Math::BigFloat, $x -> bceil() and $x -> bint() for -1 < $x < 0
returned -0. Negative zero is never used by Math::Big(Int|Float), and care
has been taken to avoid it, so this bug is surely an oversight.

Explicitly specify the backend (lib => 'Calc') in t/mbimbf.t for easier
release management of the backend distributions.

Add "use warnings" to test scripts, since Perl 5.6.2 is required anyway, and
"use warnings" was introduced in Perl 5.6.1.

Modified test scripts so the difference between the test files in the
Math-BigInt distribution and the backend distributions are as few and as
small as possible. This makes for easier release management.
