bignum 0.65

on Perl CPAN

Restore the upgrading and downgrading in "bignum", with the exception of
upgrading from Math::BigFloat to Math::BigRat, which I couldn't make sense
of. Now, both integer literals and integers (and Infs and NaNs) that are the
result of a computation become Math::BigInt objects, and both non-integer
literals and non-integers that are as a result of a computation become
Math::BigFloat objects. The classes used for literal integers and non-
integers during compile-time are configurable, as well as the classes used
for downgrading and upgrading during runtime.

Add the "bigfloat" pragma, which converts all numeric literals to
Math::BigFloat objects. This is consistent with the "bigint" pragma, which
converts all numeric literals to Math::BigInt objects, and the "bigrat"
pragma which converts all numeric literals to Math::BigRat objects.
