In Processing I have this code:

int numberOfSteps = 20;
float numberOfStepsCalculated = (1/20);
println(numberOfStepsCalculated);

But my print keeps returning 0.0

I can not figure out why!

Thanks for my dumb question

Integer divison. 

float numberOfStepsCalculated = (1.0f / numberOfSteps); // 20

When you divide two int(s) the result is an int (or 0). You then widen the result to a float (or 0.0). Promote one of the values in the calculation to a float and you'll get a float result.
