The difference between infinity and NaN (not a number)

Question

The difference between infinity and NaN (not a number)

When does java print infinity and when does it print NaN?

Why is 1.0 / 0.0 infinity, but ((1.0 / 0.0) - (1.0 / 0.0)) NaN and 0.0f / 0.0f NaN?

What is the difference between the two?
