This is a bug report for perl from andreas.koenig.7os6VVqR@franz.ak.mind.de,
generated with the help of perlbug 1.36 running under perl 5.10.0.

[Please enter your report here]
CPAN testers have found 12 versions of perl that believe that X89.2 is larger than X90, with X being 1234567891234567. This is not limited to use64bitint architectures and 64 bit boxes are not behaving better. Appending a .0 to the integer solves the bug on all architectures but this is considered unperlish at best.
Here are a few data points about the twelve perls. By prepending http://www.nntp.perl.org/group/perl.cpan.testers/ to the first column you get the full report to see further details.
