Re^8: number array with space

if ($array[$i] =~ /\d+/){ <your code> }

But that matches non-numbers:

>perl -wMstrict -le
"print 'this is a number?!?' if 'x9x' =~ /\d+/;
"
this is a number?!?

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).
