Syncing with recent Math-BigInt

[pjacklam]

There are changes to the Math-BigInt distribution that affects the CryptX distribution and causes a few tests to fail when CryptX is tested with the most recent Math-BigInt distribution installed.

• I noticed that Math::BigFloat->bdiv(), when called in list context, does floored division, except when the denominator is 1. This inconsistency has been removed, so that in list context, Math::BigFloat->bdiv() always does floored division. This change causes 4 tests to fail in t/mbi_ltm_bigfltpm.t.

• For my own convenience, I added an _scmp() method to the backend library. This method does signed comparison, c.f. _acmp() which compares absolute values and ignores the signs. I cannot see that this change causes any tests to fail, but I wanted to inform you anyway.

should be fixed in CryptX-0.085_002

Thanks. CryptX-0.085_002 passes all tests with Strawberry Perl 5.40.2.1-beta1.
