thank you for comment @ekansh_devs

Interesting approach. Here’s what I’d do to determine if a value is a number:

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

this is also a good way to check if is number in less blocks
nice @tatiang

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:

4
29
heythere29
M8

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