| InvalidOperationException | any x is signaling NaN |
| InvalidOperationException | any combination of elements is (±∞, ±0.0) or (±0.0, ±∞) |
| InvalidOperationException | there are two products resulting in infinities of different sign |
| OverflowException | result is too big to be represented |
| UnderflowException | result is too small to be represented |
| InexactException | result is inexact |
Sums xi * yi using a higher precision, rounding only once at the end.
