in thread string functions

Is this what you want? Sorry, but your speccs are not very clear ...

2A2B2C = 28.423828125 4AC = 5.315625 ABC = 2.165625 BC = 2.8875

This was produces by the following code (adapted from holiy's solution):

use strict; use warnings; my @p = (1.5, 2.5, 3.5 ); my @m = (0.5, 0.55, 0.60); sub calc { my $i = shift || 1; my $idx = ord(shift)-65; return $m[$idx] * ($p[$idx]**$i); } for my $str (qw/2A2B2C 4AC ABC BC/) { my $res = 1; while ($str =~ /(\d)?([A-Z])/g) { $res *= calc($1, $2); } print "$str = $res\n"; }

    i have the str in an excel file which has approximately 400 entries like 4ABC,BC,3C,2BC,3B,5C,B2CD,3AB2C,3A,C,D... etc. But the maximum no. of characters is 6.How can i pass it.
      1. mark the column in Excel and copy
      2. paste the column into the DATA section of the follwoing script (replacing the example that is already there)
      3. run the script and redirect the output into a file called output.csv
      4. open the output.csv in Excel and copy and paste from there
      use strict; use warnings; my @p = (1.5, 2.5, 3.5 ); my @m = (0.5, 0.55, 0.60); sub calc { my $i = shift || 1; my $idx = ord(shift)-65; return $m[$idx] * ($p[$idx]**$i); } for my $str (<DATA>) { chomp($str); my $res = 1; while ($str =~ /(\d)?([A-Z])/g) { $res *= calc($1, $2); } print "$str,$res\n"; } __DATA__ 2A2B2C ABC
      You have to make sure, though, that your @p and @m Arrays are expanded to the appropriate number of elements, corresponding to the number of letters from the alphabet that you use. So if you eg. use the letters from A to D then @p and @m should both have 4 elements.
