Are you sure? The formula you posted can be optimized to get rid of 32-bit
arithmetic. However, depending on relative magnitudes of the variables,
the overall result could be less than 1. This may falsely lead you to
believe that floating point arithmetic is necessary.

I think before we can help, we need to know 1) the magnitude of the
variables 2) what (exactly) the output of the formula is for. You mention
trig stuff, but is it arctan, sine, or what?

When it comes to math, there are many ways to optimize...
