    The section at the beginning is bad excel advice because it only works on positive numbers. INT works by rounding DOWN to the nearest integer. So if you had 1.3, and used INT on it, you'd get 1, which is what you want. But if you had -1.3 and used INT on it, you'd get -2, which is NOT what you want.

    If you want to separate the integer from the decimal, should use TRUNC instead of INT. If you used TRUNC on 1.3 you'd get 1. And if you used TRUNC on -1.3, you'd get -1. Then you can do as per the original instructions and subtract the integer form the original number to get the separated decimal.
