# _mm256_insertf128_ps

Inserts 128 bits of packed float32 values. The corresponding Intel® AVX instruction is VINSERTF128.

## Syntax

extern __m256 _mm256_insertf128_ps(__m256 a, __m128 b, int offset);

## Arguments

a | 256-bit float32 source vector
b | 128-bit float32 source vector
offset | an integer value that represents the 128-bit offset where the insertion must start

## Description

Performs an insertion of 128 bits of packed single-precision floating-point values (float32 values) from the second source vector b, into a destination at a 128-bit offset specified by the offset parameter. The remaining portions of the destination are written by the corresponding elements of the first source vector a.

## Returns

Result of the insertion operation.
