fpgetmask(3C)

NAME
     fpgetmask, fpgetround, fpgetsticky, fpsetmask, fpsetround, fpsetsticky -
     fetch/set subfields of floating-point control status register of MIPS
     floating-point units

SYNOPSIS
     #include <ieeefp.h>

     #define fp_except       int

     typedef enum    fp_rnd {
         FP_RN = 0,  /* round to nearest representable number,
                        tie -> even */
         FP_RZ = 1,  /* round toward zero (truncate) */
         FP_RP = 2,  /* round toward plus infinity   */
         FP_RM = 3   /* round toward minus infinity  */
         } fp_rnd;

     fp_except fpgetmask(void);

     fp_rnd    fpgetround(void);

     fp_except fpgetsticky(void);

     fp_except fpsetmask(fp_except);

     fp_rnd    fpsetround(fp_rnd);

     fp_except fpsetsticky(fp_except);

DESCRIPTION
     These routines fetch/set various subfields of the floating-
     point control status register of the floating-point unit.

     fpgetmask returns the current exception mask.

     fpgetround returns the current rounding mode.

     fpgetsticky returns the logged exceptions.

     fpsetmask sets the exception mask, returning the previous
     exception mask.  Any sticky bit whose corresponding mask bit is being
     enabled is cleared.

     fpsetround sets the rounding mode, returning the previous
     rounding mode.

     fpsetsticky sets the logged exceptions, returning the previous logged
     exceptions.

NOTES
     All of these routines take and/or return their values right justified.
