A Rubber Ball

A rubber ball is tossed off the top of a 90 foot building. Every time it bounces, it goes back up half way. How many bounces will the ball take before it stops?

Technically and theoretically, the answer should be infinite. That's because you can always halve a number infinitely without it ever becoming 0... Am I right?
