What's the best way to check if a data point is a number?

Hello

I’d like to write a data point into an airtable field. It’s supposed to be a number, but sometimes it is not.

How can I check if it’s a number? And if it’s not a number return 1.

ChatGPT suggests using “isnumber” but I can’t find anything in the help section regarding isnumber (here: https://help.make.com/)

Therefore chatGPT’s suggestion doesn’t work:

if(isnumber(parseNumber({{13.employee_count}})); parseNumber({{13.employee_count}}); 1)

Do you have a tip how to do this?
Thank you!
