fma(a: Int, b: Int, c: Int) -> Int

Performs fma (fused multiply-add) on the inputs.

The result is (a * b) + c.

Args:

• ​a (Int): The first input.
• ​b (Int): The second input.
• ​c (Int): The third input.

Returns:

Int: (a * b) + c.

fma[dtype: DType, width: Int, //](a: SIMD[dtype, width], b: SIMD[dtype, width], c: SIMD[dtype, width]) -> SIMD[dtype, width]

Performs elementwise fma (fused multiply-add) on the inputs.

Each element in the result SIMD vector is $(A_i\ast B_i)+C_i(A\_i\; *\; B\_i)\; +\; C\_i$, where $A_{i}A\_i$, $B_{i}B\_i$ and $C_{i}C\_i$ are elements at index $ii$ in a, b, and c respectively.

Parameters:

• ​dtype (DType): The dtype of the input SIMD vector.
• ​width (Int): The width of the input and output SIMD vector.

Args:

• ​a (SIMD): The first vector of inputs.
• ​b (SIMD): The second vector of inputs.
• ​c (SIMD): The third vector of inputs.

Returns:

SIMD: Elementwise fma of a, b and c.
