FP_IEEE_DENORM_GET_ Procedure

Summary

The FP_IEEE_DENORM_GET_ procedure reads the IEEE floating-point

denormalization mode.

Syntax for C Programmers

Syntax for TAL Programmers

Parameters

DeNorm output

INT(32)

The denormalization control mode.

DeNorm 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>

fp_ieee_denorm FP_IEEE_DENORM_GET_ (void);

?source $system.system.kfpieee

DeNorm := FP_IEEE_DENORM_GET_ ;

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.
