POSIX::isdigit() returns 1 for the empty string #11148
Comments
From perlbug@cg.cjb.netCreated by perlbug@cg.cjb.netPOSIX::isdigit() returns 1 for the empty string which is $ perl -MPOSIX -e 'print isdigit(""), "\n"' That's probably because RETVAL is initialised to 1 in POSIX.xs Verified with Perl 5.8.8, 5.10.1 and 5.12.3 Perl Info |
From Mark@Overmeer.net* Robert Lang (perlbug-followup@perl.org) [110224 08:33]:
Although POSIX.pod says: isdigit This is identical to the C function, except that it can apply that is not true. There is very little the same as in the C function The real way the implementation should be described is more like: isdigit Returns false if the string only contains digits. All these "isXXXX" functions are implemented that way. * DO NOT USE POSIX::isdigit() but regexes * Mark Overmeer MSc MARKOV Solutions |

I also agree it's best to not change the behavior now of these old, essentially obsolete functions.
