[libc][math] Add float-only option for atan2f. (#122979) 2025-02-11T22:36:24+00:00 lntue lntue@google.com 2025-02-11T22:36:24+00:00 fd41393e2e6a32a7fcacdd0779f70964689d01ec 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.
