I have been stuck on writing the is_int function for a few days and I would like an explanation of the part just before the instructions where it says:
"If the difference between a number and that same number rounded down is greater than zero, what does that say about that particular number?"
Would someone help me understand what they are trying to say? I feel like if I understand this bit, I'll be able to solve it easily. I don't want any code, just another way of thinking of how to solve the problem.
