inline fun fmaDot3(a0: Double, b0: Double, c0: Double, a1: Double, b1: Double, c1: Double, a2: Double, b2: Double, c2: Double, a3: Double, b3: Double, c3: Double, a4: Double, b4: Double, c4: Double, a5: Double, b5: Double, c5: Double): Double(source)

Computes the dot product of three 3-dimensional vectors, combined with fused-multiply-add (FMA) operations for increased precision by avoiding intermediate rounding errors.

The formula applies FMA repeatedly for the components of the vectors: result = fma(a0, b0 * c0, fma(a1, b1 * c1, ... fma(a5, b5 * c5, 0.0) ...))

Return

The computed dot product of the vectors using fused-multiply-add precision.
