v0.013 Development Version

• v0.013_007: CPAN Testers for a slew of errors for v0.013_006, so fix those FIXED = https://rt.cpan.org/Ticket/Display.html?id=117163
  • BUG DESCRIPTION: in some configs, the 09-signbit and 10-copysign values have wrong sign
  • added isCoreAbsWrongForNegNaN() to indicate systems for which CORE::abs() has the wrong sign.
  • t\09-signbit: Use that to skip the NaN tests relying on CORE::abs().
  • t\10-copysign: Use absolute() instead of abs() for verifying the magnitude copied correctly from argument x.
• v0.013_006: fixing isSignaling bug in test suite FIXED BUG = https://rt.cpan.org/Ticket/Display.html?id=117041
  • add isSignalingConvertedToQuiet() to indicate implementations that make it quiet
  • Test::More::skip() t/07 iff isSignalingConvertedToQuiet and (isSignaling or class eq signalingNaN)
  • Test::More::skip() t/08 iff isSignalingConvertedToQuiet and (one signaling other quiet)
• v0.013_005: adding negate(), abs(), copySign() IN PROGRESS = https://rt.cpan.org/Ticket/Display.html?id=116155
  • negate(), absolute(), copySign() working and tested
  • CORE::abs() confirmed to be equivalent to absolute(); documented as such (and still remains in the test suite)
• v0.013_004: adding totalOrder, totalOrderMag() IN PROGRESS = https://rt.cpan.org/Ticket/Display.html?id=116155
  • totalOrder() working as I expect: use the trick for both-NaN to convert them to a real number by changing the exponents to the same value, and doing a numerical comparison
  • totalOrderMag() = flip the sign bit, then call totalOrder
• v0.013_003: adding 5.7.2 informational operations, adding coverage in t/07*.t; IN PROGRESS = https://rt.cpan.org/Ticket/Display.html?id=116155
  • nextup(), nextdown(), nextafter() => renamed to nextUp(), nextDown(), nextAfter() to agree with IEEE Std 754-2008 nomenclature.
  • finished the isXxx(): isSignMinus .. isCanonical;
  • finished: class(), radix()
  • TODO: totalOrder(), totalOrderMag()
• v0.013_002: add the constants; add test coverage for :constants FIXED = https://rt.cpan.org/Ticket/Display.html?id=116154
• v0.013_001: swap out old ulp() for ulp_by_div(), which benchmarks said ran 50-60% more effeciently; still passes existing tests. FIXED = https://rt.cpan.org/Ticket/Display.html?id=116153
