Like Bandinage said there is millions (including decimals)

But if you want to know the difference between them you should've said that.

64 - 99 

64 - 100

100 - 64 =36 - 1 = 35 I think....

Q: whats in-between 63 and 99?

A: lots of numbers, an infinite lot of numbers, in fact.

Here are half a dozen examples:

63.11
