For targets that have single precision FPU but not double precision FPU
such as Cortex M4, only using float-float in the intermediate
computations might reduce the code size compared to using double. In
this case, when the exact pass is skipped, the float-only option for
atan2f implemented in this PR reduces the code size of this function by
~1 KB compared to the double precision version.
