If the maximum value of your program bar is zero, is it full? Is it empty? This is a design choice, and when you've chosen, just test for max == 0 and deploy your answer. share|improve this answer answered Oct 1 '08 at 22:57 Adam Wright 39.9k8102137 add a comment| up vote 6 down vote You can throw an exception. You can do int percent = ( max > 0 ) ? (100 * position) / max : 0; You can choose to do nothing instead of assigning a value to percent. man

And as you know (probably, if not you do now), you can't divide by 0.

This tip shows the different results of dividing different type numbers with Zero Download source code - 746 B Introduction In this tip, I would like to point out that dividing a number by zero doesn't always raise an exception as is generally taken for granted.
