* use c++20 concepts and numbers for lmms_constants.h * replace lmms::numbers::sqrt2 with std::numbers::sqrt2 * replace lmms::numbers::e with std::numbers::e Also replace the only use of lmms::numbers::inv_e with a local constexpr instead * remove lmms::numbers::pi_half and lmms::numbers::pi_sqr They were only used in one or two places each * replace lmms::numbers::pi with std::numbers::pi * add #include <numbers> to every file touched so far This is probably not needed for some of these files. I'll remove those later * Remove lmms::numbers Rest in peace lmms::numbers::tau, my beloved * Add missing #include <numbers> * replace stray use of F_EPSILON with approximatelyEqual() * make many constants inline constexpr A lot of the remaining constants in lmms_constants.h are specific to SaProcessor. If they are only used there, shouldn't they be in SaProcessor.h? * ok then, it's allowed to be signed * remove #include "lmms_constants.h" for files that don't need it - And also move F_EPSILON into lmms_math.h - And also add an overload for fast_rand() to specify a higher and lower bound - And a bunch of other nonsense * ok then, it's allowed to be inferred * ok then, it can accept an integral * fix typo * appease msvc * appease msvc again * Replace linearInterpolate with std::lerp() As well as time travel to undo several foolish decisions and squash tiny commits together * Fix msvc constexpr warnings * Fix msvc float to double truncation warning * Apply two suggestions from code review Co-authored-by: Dalton Messmer <messmer.dalton@gmail.com> * Apply suggestions from code review Co-authored-by: Dalton Messmer <messmer.dalton@gmail.com> * fix silly mistake * Remove SlicerT's dependence on lmms_math.h * Allow more type inference on fastRand() and fastPow10f() * Apply suggestions from code review Co-authored-by: Dalton Messmer <messmer.dalton@gmail.com> * Clean up fastRand() a little bit more --------- Co-authored-by: Dalton Messmer <messmer.dalton@gmail.com>
