How to check for nan

PB____

Is there a way to check if a value is not a number nan? I could prevent using negative values with sqrt, so no problem if it's not possible, but I noticed that even sqrt(-1) == sqrt(-1) equals false...

I do agree with the choice to tolerate weird input values like this, since it aligns well with the use-case for Fuze. It's just a little unexpected quirk i happened to run into.

silly idea, what about: (partially tested)

n = sqrt(-1)
if (str(n) == "nan") then
   print("is no valid number")
endif

Nice, that works 👍
