Is there a more efficient way to determine if a single character is a
number versus a non-number?

I use the ASC() function to check for the ASCII values between 48-57?

Thanks in advance

Your method is one of the "safest" methods.

Someone may suggest a more "standard" method of using "Isnumeric", for
example:

Isnumeric("1")

However, this is not always "safe", especially in older versions of Excel
(e.g. Excel 5 and 97) Therefore, to test single characters, it's not worth
taking the risk. So, I think using the ASC test is more safe.

AP,
If you wish to be pedantic, what does "½" or "?" mean to you ?
