Arithmetic Operations (Floating Point)

  • Article

Microsoft Specific

The operations listed in the following table are followed by descriptions of each intrinsic.

SSE2 intrinsics use the __m128, __m128i, and __m128d data types, which are not supported on Itanium Processor Family (IPF) processors. Any SSE2 intrinsics that use the __m64 data type are not supported on x64 processors.

The emmintrin.h header file contains the declarations for the SSE2 instructions intrinsics.
