Fix RT 62764: Math::BigFloat->bcmp() fails.
Why: The Math::BigFloat->bcmp() method returns the wrong result when the
exponent is too large to be represented exactly as a Perl numerical
scalar. In such cases, bcmp() returns 0 because it fails to distinguish
between the two exponents.
How: With this fix, bcmp() does not convert the exponents to Perl
numerical scalars, but keeps them as arbitrary precision integers, thus
returning the correct result regardsless of the number of digits in the
exponent.
Test: Two tests added. These tests fail with the old code.
Files:
- lib/Math/BigFloat.pm: New version of bcmp().
- t/bigfltpm.inc: Add two tests confirming desired behaviour.
- t/bare_mbf.t: Increment test count.
- t/bigfltpm.t: Increment test count.
- t/sub_mbf.t: Increment test count.
- t/with_sub.t Increment test count.
