A fixed point math header-library for C, under a liberal license.

Features

  • Fixed point math library
  • Requires a fairly modern C compiler with uint32_t and uint64_t
  • 32-bit and 64-bit precision support (for compilers with __int128_t extensions like gcc)
  • Arbitrary precision point (e.g. 24.8 or 32.32)
  • Pure header-only
  • Pure integer-only (suitable for kernels, embedded CPUs, etc)

User Reviews

  • fixedpt_sqrt() returns 0 for any number if FIXEDPT_BITS == 64. To fix this, inside fixedpt_sqrt define variables l and s as fixedpt instead of int.
  • Hi. I dont know how to submit code here but the fixedpt_str 'negation' should look like this: if (A < 0) { str[slen++] = '-'; A=~A; //A *= -1; }
  • this library works very well. i Have modified the code to get a higher precision by the sin function. is there an explanation to the code for sin function. don't unterstand every row regards eric
