asinf4

NAME

asinf4 - return arc sines of float elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector float asinf4(vector float x);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <asinf4.h>
vector float _asinf4(vector float x);
Parameters  
x input vector

DESCRIPTION

The asinf4 function returns a vector of the arc sines of the elements of x. Inputs must be within the interval [-1,+1].

RETURN VALUE

The function asinf4 returns a float vector in which each element is defined as:
  • the arc sine of the corresponding element of x, if the element of x is within the interval [-1,+1],
  • undefined otherwise.
Each element in the return vector is expressed in radians.
