SIMD Datatypes AVX Programming have these types __m128 : 128bit data type that have 4 floats __m128d : 128bit data type that have 2 doubles __m128i : 128bit integers(but differs dependes on the bit system) __m256 : 256bit data type that have 8 floats __m256d : 256bit data type that hve 4 doubles __m256i : 256bit integers
