Yes, but ----

As you have already discovered, the compiler is likely to pull in a heap of
floating point code to do the calculation (slow) and then convert it to
fixed point. Now this may be fine for a
get-you-up-and-running-to-test-the-idea type solution, but is not an
efficient way to do it, and also suggests that you may be missing or
introducing some underlying side effect which could have an effect on the
end performance.

Do think through the math and how to do it in fixed point (faster) and what
the calculation is actually doing.
