float zero=0;
if(zero/abs(zero)==zero/abs(zero)){ellipse(200,200,200,200);}
Is this a processing fail-safe or a universal thing across computer code?
Edit: wait nevermind, it’s a stupid question since c++ can show infinity when displaying divide by zero results.
I don’t think it’s a stupid question ! 
So I’ve tried print(9/0); !
Processing :

“Aritmetic Exception : /0”

No idea because the Python module does not start with Processing 3 and this line crashes Processing 4.4.4

According to Mr or Mrs Internet, the division by zero in Python gives: ZeroDivisionError:division by zero.
So, When there is A / B, it may be good to test before if B=0 (if it may happens).
