Use the math lib, or implement a table-based interpolation yourself.

Consider an integer-based solution.

You did not even mention the MCU you are working with.

Why do you want to avoid math.h ?

Have you looked at: https://www.keil.com/pack/doc/CMSIS/DSP/html/group__groupFastMath.html

Did you do any research yourself?

eg, google found this: https://digital.library.unt.edu/ark:/67531/metadc283001/
