# _mm256_and_si256

Performs bitwise logical AND operation on signed integer vectors. The corresponding Intel® AVX2 instruction is VPAND.

## Syntax

extern __m256i _mm256_and_si256(__m256i s1, __m256i s2);

## Arguments

s1 | signed integer vector used for the operation
s2 | signed integer vector also used for the operation

## Description

Performs a bitwise logical AND operation of the signed integer elements of source vector s1 and corresponding elements in source vector s2, and stores the result in the destination vector. If the corresponding bits of the first and second vectors are 1, each bit of the result is set to 1, otherwise it is set to 0.

## Returns

Result of the bitwise logical AND operation.
