_mm_castsi128_ps
Microsoft Specific
Applies a type cast to reinterpret four 32-bit integers passed in as a 128-bit parameter as packed 32-bit floating point values.
__m128 _mm_castsi128_ps(
__m128i a
);
Parameters
- [in] a

Remarks
The 128-bit return value r is a copy of the 128-bit parameter a, but cast as four 32-bit floating point values. This intrinsic changes one data type to another without performing any conversion.
This intrinsic does not map to any specific machine instruction.
