hi,
How to get the decimal point of the float or doubld variable.
ex.
100.23 = .23 or 23
.12 = .12 or 12

thanks ,

There might be a cleaner way, but this should at least get you the result. Just be aware, that you are boud to get small rounding errors here:

            float myFloat = 15.12f;
            int myInt = (int)myFloat;
            float myAnswer = myFloat - (float)myInt;

An other way could be to cast it to string, and then find the . sign and then use SubString.

That gives you 0.1199999.

This is equally ugly but gives you 0.12.

float value = 15.12f;
decimal decimalPart = (decimal) value - (decimal) Math.Floor(value);
