- x
- Double
The number to be multiplied with y.
- y
- Double
The number to be multiplied with x.
- z
- Double
The number to be added to the result of x multiplied by y.
Returns
(x * y) + z, rounded as one ternary operation.
Remarks
This computes (x * y) as if to infinite precision, adds z to that result as if to infinite precision, and finally rounds to the nearest representable value.
This differs from the non-fused sequence which would compute (x * y) as if to infinite precision, round the result to the nearest representable value, add z to the rounded result as if to infinite precision, and finally round to the nearest representable value.
