in reply to regex and string functions help needed.

The below code is developed based on your logic and I am getting the following output. But I am not getting your expected output. Check whether your expected output is correct.

use strict; use warnings; my %p = (A => 2.74, B => 2.64, C => 2.5); my @range = (50,55,60,65,70,75,80,85,90); while(my $str = <DATA>){ chomp($str); print "\nInput : $str\n"; $str =~ s/(\d+)(\w)/($2 . '*') x $1/eg; $str =~ s/(\w)(\w)/$1 . '*' . $2 . '*' /eg; $str =~ s/(?!\*)$/*/; $str =~ s/(.)\*(?!\1)/"$1\*\(".$range[ord($1) - 65]."\/100\)\*"/eg +; $str =~ s/\*+$//; $str =~ s/$_/$p{$_}/g for (keys %p); print "Expression: ".$str ."\n"; print "Output : ",eval$str ,"\n\n"; } __DATA__ 4ABC 2A2B2C 3C ABC Output is: Input : 4ABC Expression: 2.74*2.74*2.74*2.74*(50/100)*2.64*(55/100)*2.5*(60/100) Output : 61.38045890064 Input : 2A2B2C Expression: 2.74*2.74*(50/100)*2.64*2.64*(55/100)*2.5*2.5*(60/100) Output : 53.96012424 Input : 3C Expression: 2.5*2.5*2.5*(60/100) Output : 9.375 Input : ABC Expression: 2.74*(50/100)*2.64*(55/100)*2.5*(60/100) Output : 2.98386

    My code in Re^3: string functions (in valavanp's original thread) gets to the same results - so we have both understood our fellow monk incorrectly (?) but in the same way :)

    Update: So, valavanp, it would really help if you could spell out for us step by step how you arrive at your expected values ...
