FE_ALL_EXCEPT

#define FE_ALL_EXCEPT   31

FE_DIVBYZERO

#define FE_DIVBYZERO   2

FE_DOWNWARD

#define FE_DOWNWARD   1

FE_INEXACT

#define FE_INEXACT   16

FE_INVALID

#define FE_INVALID   1

Minimal <fenv.h> for XenevaOS: quickjs.c includes it but only uses the rounding mode constants / no-op entry points, none of which map to OS support in XEClib. IEEE-754 default rounding is assumed throughout.

FE_OVERFLOW

#define FE_OVERFLOW   4

FE_TONEAREST

#define FE_TONEAREST   0

FE_TOWARDZERO

#define FE_TOWARDZERO   3

FE_UNDERFLOW

#define FE_UNDERFLOW   8
