But it's still only a warning, it does not break anything, it's Perl telling
you "you're coding like a moron, but I get what you mean" :

$ perl -Mwarnings -e 'print 3 <=> "2.49_01" '
Argument "2.49_01" isn't numeric in numeric comparison (<=>) at -e line 1.
1
$ perl -Mwarnings -e 'print 2 <=> "2.49_01" '
Argument "2.49_01" isn't numeric in numeric comparison (<=>) at -e line 1.
-1
