fma

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 $(A_i * B_i) + C_i$ , where $A_i$ , $B_i$ and $C_i$ are elements at index $i$ 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[dtype, width]): The first vector of inputs.
b (SIMD[dtype, width]): The second vector of inputs.
c (SIMD[dtype, width]): The third vector of inputs.

Returns:

SIMD[dtype, width]: Elementwise fma of a, b and c.
