% (modulo) Math Operators Web & Application int a = 20%100; // Sets a to 20 int b = 20%100; // Sets b to 20 int c = 75%100; // Sets c to 75 int d = 275%100; // Sets d to 75 float a = 0.0; void loop() { background(204); a = (a + 0.5)%width; line(a, 0, a, height); } Calculates the remainer when one number is divided by another. It is extremely useful for keeping numbers within a boundary such as keeping a shape on the screen. value1%value2 value1 int value2 int / (divide) 1.0 Operator PDE
