NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     #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    [Toc]    [Back]

     These routines fetch/set various subfields	of the floatingpoint
 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.
