Question

What am I missing?

float stepSize = 0.0f;
int activeCircleRadius = 10;
int numSteps = 24;

AiLog.v("init activeCircleRadius " + activeCircleRadius + " numSteps "
                + numSteps);
stepSize = activeCircleRadius / numSteps;
AiLog.v("stepSize is " + stepSize);

stepSize is always zero in the log after the operation. Does it have to do with dividing a float by an int?

Answer 1

Here both variables are integers so you are performing integer division:

activeCircleRadius / numSteps

The result of integer division is an integer. The result is truncated.

To fix the problem, change the type of one (or both) variables to a float:

float stepSize = 0.0f;
float activeCircleRadius = 10;

Or add a cast to float in the division expression:

stepSize = (float)activeCircleRadius / numSteps;
