If I have understood OP's question correctly,he wont to do this:
e.g
3.2456-3.1232=0.0224.
Now what OP wont is to multiply this result with such number that it becomes a integer
0.0224*10^4=224.
Am I right,muralick?

If I'm rigth,then you will need to analyse resulting float.To determine all important parts,as:
what is a integer value of that float,how much there are decimal numbers behind decimal point.For this analyses, because of float number arithmetic, you will need to input it as a string,analyze it and then convert to the float number.
