Changes for version 0.93 - 2021-01-12
- The test is_deeply() does string comparison, so avoid negative zeros in test data and output from tests. Also round test output where the output may be slightly off from an integer.
- Require Math::Trig version 1.06 so Math::Trig::Inf() is available.
- Update the SUPPORT section to reflect that CPAN RT will be closing down on 1st March 2021.
- Add support for negative integer powers in mpow().
