vec_extract_exp

Purpose

Returns a vector that contains the exponent of the given vector.

This built-in function is valid only when -qarch(-mcpu) is set to utilize the POWER9™ technology and the altivec.h file is included.

Syntax

d=vec_extract_exp(a)

Result and argument types

The following table describes the types of the returned value and the function arguments.

Table 1. Types of the returned value and function argument
d a
vector unsigned int vector float
vector unsigned long long vector double

Result value

Each element of the result is extracted from the exponent field of the corresponding element of a.

Note: The extracted exponent of a is treated as a biased exponent in accordance with the format specified by IEEE Standard for Binary Floating-Point Arithmetic, IEEE Std. 754, without further processing.
