Arithmetic Operations (Floating-Point SSE2 Intrinsics)

Microsoft Specific

The intrinsics listed in the following table are followed by a description of each intrinsic.

SSE intrinsics use the __m128, __m128i, and __m128d data types, which are not supported on Itanium Processor Family (IPF) processors. Any SSE intrinsics that use the __m64 data type are not supported on x64 processors.

The header file xmmintrin.h contains the declarations for the SSE intrinsics.
