If you multiply a text string by zero you’ll get NaN or possibly null. If you multiply any number by zero, you’ll get zero.

Thanks. One drawback of your approach is that I’m pretty sure if the last character in the text string is a number, it will evaluate the entire string as a number. So these would all be numbers:

You’d need a variable that counts the number of found numeric digits/characters and then compares that to the length of the string.
