The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl libc, some BSD flavours) are not exactly representable, i.e. (double)DBL_MAX == DBL_MAX is false This violates (at least some interpretations of) the C99 standard and breaks code (e.g. in vf_fps) like double f = DBL_MAX; [...] if (f == DBL_MAX) { // f has not been changed yet [....] } |
