converting strings into numerical or string data depending on the contents [message #81583]

I'm looking for a way to elegantly transform string values:
(a) keeping it as string-type when the string does not contain only numbers
(b) convert into numeric-type data when appropriate.

The basic IDL type-casting routines {fix(), double(), etc.} spit out string-conversion complaints (non-fatal errors) whenever I apply them to arbitrary 'non-numerical' strings.

Is there a better way to do this than stregex()? (That is, am I going to have to learn to use stregex() to accomplish this filtering?)
