Changes for version v0.011_004

  • Ran Devel::Cover's cover() script:
    • Tools.pm#248: (SNAN vs QNAN) only one of the two conditions is covered (because this machine cannot do SNAN) = no fix
    • Tools.pm#269: (SNAN vs QNAN) only one of the two conditions is covered (because this machine cannot do SNAN) = no fix
    • Tools.pm#362: (unreachable return) was a holdover from debugging; deleted. = deleted
    • Tools.pm#418: (msb & 0x8000000) only tests one (only one sign in that direction) = no fix (yet)
    • Tools.pm#420: (msb & 0x8000000) only tests one (only one sign in that direction) = no fix (yet)
  • use 5.8.5: perlver says that the only requirement for 5.8 is the constant hash
    • v0.011_002: attempt to lower to 5.6.0, and change from constant hash to multiple `use constant` lines
    • v0.011_003: edit Makefile.PL to also 'use 5.006' instead of '5.008005'
    • v0.011_004: edit Makefile.PL to use {MIN_PERL_VERSION} = '5.6.0' instead of '5.8.5'
  • Test suite for :raw754 now switches to '==' comparison for numeric arguments, and check for 64bit NV
    • bug @ <https://rt.cpan.org/Public/Bug/Display.html?id=116004>; still exists in v0.011_001
    • v0.011_002: change test suite to use a '%+24.16e' got eq expect, rather than raw got == expect
    • v0.011_002: issue did not appear during CPAN Testers, so believed fixed
  • nextup():
    • bug @ <https://rt.cpan.org/Public/Bug/Display.html?id=116006>,
    • could not replicate; but adding diagnostics showed that when LSB underflows (goes to -1), the hexification is too many F's; perhaps on some systems, that was being misinterpreted when the two were being recombined, so masked the MSB and LSB before merging
    • v0.011_001: issue did not appear during CPAN Testers, so believed fixed
    • v0.011_002: issue did not appear during CPAN Testers, so believed fixed
  • Test suite for :floatingpoint now converts SNAN to expect /[SQ]NAN/, because it doesn't really matter that much whether Perl silences a signaling NAN
    • bug @ <https://rt.cpan.org/Public/Bug/Display.html?id=116005>
    • v0.011_001: issue did not appear during CPAN Testers, so believed fixed
    • v0.011_002: issue did not appear during CPAN Testers, so believed fixed
