FP_IEEE_ROUND_SET_ Procedure

Summary

The FP_IEEE_ROUND_SET_ procedure sets the current rounding mode.

Syntax for C Programmers

Syntax for TAL Programmers

Parameters

NewMode input

INT(32)

The 32-bit rounding mode code.

The rounding mode can have one of the following values:

Note. This procedure is supported in the G06.06 RVU and all subsequent G-series RVUs. IEEE

floating-point is available on all S-series processors except S70000 servers with NSR-G processors.

#include <kfpieee.h>

void FP_IEEE_ROUND_SET_( fp_ieee_round new_mode );

?source $system.system.kfpieee

FP_IEEE_ROUND_SET_ ( NewMode ); ! i

FP_IEEE_ROUND_NEAREST Round toward the representable

value nearest the true result. In

cases where there are two equally

near values, the "even" value (the

value with the least-significant bit

zero) is chosen (the standard

rounding mode).

FP_IEEE_ROUND_UPWARD Round up (toward plus infinity).

FP_IEEE_ROUND_DOWNWARD Round down (toward minus infinity).

FP_IEEE_ROUND_TOWARDZERO Round toward zero (truncate).
