Hi to all!
I'm writing an assembly program that at a certain point calculates a square root, then it has to verify if the result is an integer (i.e. 2.000) or a "true" floating point number (i.e. 2.456).
How can I do this in Assembly language?

P.S.
The next week I have to take an exam about this kind of things, I hope you can help me.
