in reply to using re 'eval' for varibable math

The Math::Pari module can evaluate mathematical expressions with a more restricted syntax than perl's -- but watch out for "system()". Here's an example.

use strict; use Math::Pari qw(PARI); my $question="67.35 >= 50 && 67.35 < 80"; # Pari doesn't like white space in expressions. $question =~ s/\s+//g; my $out = PARI $question; print $out,"\n";
