Detect if a scalar is NaN

[User36]

Hey, Im at work working on a script and I run into nan is there a fuction that checks to make sure my number is a valid number so i can do something like: unless (NaNfuction($mynumber)) { #do stuff } if not is there some way other way to check? ------------ haha wow sorry excuse me. I added 350 lines to an already buggy script so im doing 1921092 things at once and I wasnt paying much attention to my nan issue
