_mm256_castpd_ps

Typecasts double-precision floating point values to single-precision floating point values. No corresponding Intel® AVX instruction.

Syntax

extern __m256 _mm256_castpd_ps(__m256d a);

Arguments

a

float64 source vector

Description

Performs a typecast operation from double-precision floating point values (float64 values) to single-precision floating point values (float32 values). This intrinsic does not introduce extra moves to the generated code. Source operand bits are passed unchanged to the result.

Returns

A vector with single-precision floating point values.
