public static class Fma

Properties

Name	Description
IsFmaSupported	Evaluates to true at compile time if FMA intrinsics are supported. Burst ties FMA support to AVX2 support to simplify feature sets to support.

Methods

Name	Description
fmadd_pd(v128, v128, v128)	Multiply packed double-precision (64-bit) floating-point elements in a and b, add the intermediate result to packed elements in c, and store the results in dst.
fmadd_ps(v128, v128, v128)	Multiply packed single-precision (32-bit) floating-point elements in a and b, add the intermediate result to packed elements in c, and store the results in dst.
fmadd_sd(v128, v128, v128)	Multiply the lower double-precision (64-bit) floating-point elements in a and b, and add the intermediate result to the lower element in c. Store the result in the lower element of dst, and copy the upper element from a to the upper element of dst.
