`if ($array[$i] =~ /\d+/){ <your code> }` [download] But that matches non-numbers: `>perl -wMstrict -le "print 'this is a number?!?' if 'x9x' =~ /\d+/; " this is a number?!?` [download] Better to use `Scalar::Util::looks_like_number()` (see this), which correctly identifies numbers like `'1.2' '1.2e3' '0e0'`, or if only decimal digits are acceptable, use the `/^\d+$/` regex (see this).
