FP_IEEE_DENORM_SET_ Procedure

Summary

The FP_IEEE_DENORM_SET_ procedure sets the IEEE floating-point

denormalization mode.

Syntax for C Programmers

Syntax for TAL Programmers

Parameters

NewMode input

INT(32)

The denormalization control mode.

NewMode can have 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_DENORM_SET_( fp_ieee_denorm new_mode );

?source $system.system.kfpieee

FP_IEEE_DENORM_SET_ ( NewMode ); ! i

FP_IEEE_DENORMALIZATION_ENABLE Denormalization in IEEE

floating point allows for

greater precision in the

representation of numbers

that are very close to zero.

This is the standard mode.

FP_IEEE_DENORMALIZATION_DISABLE The nonstandard mode.

When denormalization is

disabled, fractions that are

too small to be represented

in standard IEEE form are

represented as zero,

causing a loss of precision.
