If folks are interested in their own custom approximations, I can highly recommend Sollya [1]. Sollya has a great Remez implementation as well as a proven supremum norm (maximum error). I combined it with more traditional “loop over all 32-bit float values to also test my range reduction”, but being able to choose your error and number of coefficients is nice!
