I expect this will be due to commit ce6f496d720f6206455628425320badd95b07372, with which RT 41202 was resolved. With that commit, we can expect that expressions like "0xFF"+0 and "0b1001"+0 will numify to the same NV as POSIX::strtod("0xFF") and POSIX::strtod("0b1001") respectively. Is this a behaviour that should be changed ? For me, strtod() does not understand the '0b' prefix and simply numifies such strings to an NV of zero. C:\>perl -MPOSIX -le "@x=POSIX::strtod('0b11111'); print for @x;" 0 6 But it does understand the '0x' prefix: C:\>perl -MPOSIX -le "@x=POSIX::strtod('0xff'); print for @x;" 255 0 Cheers, Rob On Fri, Jun 28, 2019 at 12:50 AM H.Merijn Brand <h.m.brand@xs4all.nl> wrote: > On Thu, 27 Jun 2019 07:35:45 -0700, "Dan Book \(via RT\)" > <perlbug-followup@perl.org> wrote: > > > perl -Mwarnings -e 'print "0xFF" + 0, "\n"' > > Interesting > > $ perl-all -le 'print "0xFF" + 0' > Running perl-all -le print "0xFF" + 0 > > === base/perl5.6.0 5.006 x86_64-linux > 255 > === base/perl5.6.1 5.006001 x86_64-linux-perlio > 255 > === base/tperl5.6.1 5.006001 x86_64-linux-thread-multi-ld-perlio > 255 > === base/perl5.6.2 5.006002 x86_64-linux-perlio > 255 > === base/tperl5.6.2 5.006002 x86_64-linux-thread-multi-ld-perlio > 255 > === base/perl5.6 5.006002 x86_64-linux-perlio > 255 > === base/tperl5.6 5.006002 x86_64-linux-thread-multi-ld-perlio > 255 > === base/perl5.8.0 5.008 x86_64-linux > 0 > === base/tperl5.8.0 5.008 x86_64-linux-thread-multi-ld > 0 > === base/perl5.8.1 5.008001 x86_64-linux > 0 > === base/tperl5.8.1 5.008001 x86_64-linux-thread-multi-ld > 0 > === base/perl5.8.2 5.008002 x86_64-linux > 0 > > ... 0 all the way to > > === base/tperl5.28 5.028001 x86_64-linux-thread-multi-ld > 0 > === base/perl5.29.0 5.029000 x86_64-linux > 0 > === base/tperl5.29.0 5.029000 x86_64-linux-thread-multi-ld > 0 > === base/perl5.29.1 5.029001 x86_64-linux > 0 > === base/tperl5.29.1 5.029001 x86_64-linux-thread-multi-ld > 0 > === base/perl5.29.2 5.029002 x86_64-linux > 255 > === base/tperl5.29.2 5.029002 x86_64-linux-thread-multi-ld > 255 > === base/perl5.29.3 5.029003 x86_64-linux > 255 > === base/tperl5.29.3 5.029003 x86_64-linux-thread-multi-ld > 255 > === base/perl5.29.4 5.029004 x86_64-linux > 255 > === base/tperl5.29.4 5.029004 x86_64-linux-thread-multi-ld > 255 > === base/perl5.29.5 5.029005 x86_64-linux > 255 > === base/tperl5.29.5 5.029005 x86_64-linux-thread-multi-ld > 255 > === base/perl5.29.6 5.029006 x86_64-linux > 255 > === base/tperl5.29.6 5.029006 x86_64-linux-thread-multi-ld > 255 > === base/perl5.29 5.029006 x86_64-linux > 255 > === base/tperl5.29 5.029006 x86_64-linux-thread-multi-ld > 255 > > I have more perl's at home > > -- > H.Merijn Brand http://tux.nl Perl Monger http://amsterdam.pm.org/ > using perl5.00307 .. 5.29 porting perl5 on HP-UX, AIX, and openSUSE > http://mirrors.develooper.com/hpux/ http://www.test-smoke.org/ > http://qa.perl.org http://www.goldmark.org/jeff/stupid-disclaimers/ >Thread Previous | Thread Next
