in thread non numeric data

ya i figured that out , there is a possibility that numbers having - sign are not being blocked so I modified by code . please tell if it is fine or not

if (($array_H[$i] !~ /^[0-9]+$/) &&($array_H[$i] !~ /^-+$/))

I am new to perl so please pardon me for obvious mistakes
