I have variables used in math operations that have some extra non-digit data, usually just a letter following them. The math works fine, but naturally I get warnings about the argument not being numeric.
use warnings; while ($line = <DATA>){ chop($line); ($a,$b,$c,$d,$e,$f,$g)=split(",",$line); $sum = ($a+$b+$c+$d+$e+$f+$g); print $sum; } __END__ 86f,934e,92,102i,14,19,222,
The value at the end, 1469 is accurate but I'd like to take out the letters and avoid the warnings as they are not needed in my data context.
Argument "934e" isn't numeric in addition (+) at line 7, <DATA +> line 1. Argument "86f" isn't numeric in addition (+) at line 7, <DATA> + line 1. Argument "102i" isn't numeric in addition (+) at line 7, <DATA +> line 1. 1469
I tried using (s/\D//g) in various ways but I'm just getting it wrong, can this be easily done without altering each variable before the math operation individually? Please don't lecture me on strictures, this is a small example of my problem, not polished code.

      Should cpanminus be part of the standard Perl release?
