But these fractional numbers are all | floating point. What makes you think they're floating point? As opposed to fixed point with 2 digits of precision after the point? Because they are fixed point, not floating point. I think you believe any number with a fractional part such as 1.5 is floating point, but this is not so. That is just a number with a fractional part, no more. Floating versus fixed has to do with the internal representation of the value and how computatation is done with it, not whether it has a fractional part. Have a gander at this wikipedia article: http://en.wikipedia.org/wiki/Fixed-point_arithmetic It's not bad.
