Getting a divide by 0 error when using a modulus with a number below 1.

[Kittiquel]

I am trying to get a remainder of a number with a = 0.9144, rm = ry % a; however, I keep getting a divide by zero error (I believe due to the program rounding 0.9144 down to the integer 0). Is there anyway to fix this?

I think % (mod) is only used with integers.I think you need to use:

fmod(). e.g. cout<<fmod(7.6,2.5)<<endl;//prints 0.1

Thanks! I think I got it now.
