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).
