Please Help: Check to see if a string is a valid number in proced ure/function.

Is there a way to gracefully check to see if a string can be converted to a number in a procedure or function? I have tried using the TO_NUMBER(), but that just dies when I send it a string with letters in it. Is there a way to trap that error, or another way to check to see if a string is a valid number? Thank you.
