# _mm_asin_ps, _mm256_asin_ps

Calculates inverse sine value. Vector variant of asin(x) function for a 128-bit/256-bit vector argument of float32 values.

## Syntax

extern __m128 _mm_asin_ps(__m128 v1);

extern __m256 _mm256_asin_ps(__m256 v1);

## Arguments

v1 | vector with float32 values

## Description

Calculates the arc sine of vector v1 values.

## Returns

128-bit/256-bit vector with result of the operation.

### Note

Many routines in the Short Vector Math Library (SVML) are more optimized for Intel® microprocessors than for non-Intel microprocessors.
