Developer Guide and Reference



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


extern __m256 _mm256_castpd_ps(__m256d a);
float64 source vector
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.
A vector with single-precision floating point values.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
