# _mm_srav_epi32

Arithmetic shift of doubleword elements to right according variable values. The corresponding Intel® AVX2 instruction is `VPSRAVD`.

## Syntax

extern __m128i _mm_srav_epi32(__m128i s1, __m128i s2);

## Arguments

s1 | 128-bit integer source vector used for the operation
s2 | 128-bit integer source vector providing variable values for shift operation

## Description

Performs an arithmetic shift of the 32 bits (doublewords) in the individual data elements in source vector s1 to the right by the count value of corresponding data elements in source vector s2. As the bits in the data elements are shifted right, the empty high-order bits are filled with the initial value of the sign bit.

The count values are specified individually in each data element of the second source vector. If the unsigned integer value specified in the respective data element of the second source vector is greater than 31 (for a doubleword), then the destination data elements are filled with the initial value of the sign bit.

## Returns

Result of the right-shift operation.
