What does the value 1e100f stand for?

Question

I've seen this in a snippet:

animation.repeatCount = 1e100f;

my math classes are long time ago. So 1e100f would be a number with 100 zeros? So in this case the programer wanted to have infinite repeatCount?

Answer 1

According to this page on Timing, Timespaces, and CAAnimation, setting the repeatCount to 1e100f "will cause the animation to repeat until it is removed from the layer."
