* Swaps constant double values for constant float values * Use `powf` instead of `pow` for the calcualation On an ESP32 platform, this eliminates several implicit calls to the soft floating point routines __extendsfdf2, __subdf3, __floatunsidf, __muldf3, and __fixdfsi. After making the change, only the `powf` call remains. The code size also shrinks by ~80 bytes in a companion radio build.
