# _mm256_broadcastsd_pd

Takes the low packed double-precision floating-point data element from the source operand and broadcast to all elements of the result vector. The corresponding Intel® AVX2 instruction is VBROADCASTSD.

## Syntax

extern __m256d _mm256_broadcastsd_pd(__m128d val);

## Arguments

val | __m128 vector containing the 64-bit element to be broadcasted

## Description

Takes the low packed double-precision floating-point (float64) data element from the source operand and broadcasts it to all elements of the result vector. The source operand is `__m128d`; only the low 64 bits of this operand are broadcasted.

The 128-bit version of this intrinsics is _mm_broadcastsd_pd. The intrinsic's syntax is extern __m128d _mm_broadcastsd_pd(__m128d val); This intrinsic is an alias for _mm_movedup_pd() intrinsic. Please, see Double-precision Floating-point Vector Intrinsics for details.

## Returns

Return result of the broadcast operation.
