Here is what I am trying to do int z = pulseIn(2, HIGH); int y = pulseIn(2, LOW); int x = z + y; float w = z / x; int v = w * 4000; I am expecting an integer output for v: Percentage w% * 4000 = 0 to 4000. What am I missing here?

Float math using only variables, how to define decimal places?

You could also fix it by casting z or x to a float in the first case.
