in thread number array with space

Simply go for regex then:

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

    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).

      sorry..
      if $array[$i] =~ /^\d+$/ { <block of code> }
