Perl interface to the GMP integer functions
Changes for 0.57
- Expand cross-class overloading to include +=, -=, *=, /=, and **= operations, conditionally available only when $Math::GMPz::RETYPE has been set to 1.
- Fix bug in t/mpfr_NV_checks.t. (The script needs Math-MPFR-4.07 or later.)
- Simplify overloading of '++' and '--'.
- Add new functions Rmpz_cmp_sj and Rmpz_cmp_uj (but only for builds where IVSIZE > LONGSIZE).
- Modify Rmpz_cmp_IV (to utilize Rmpz_cmp_sj and Rmpz_cmp_uj where applicable).
