About the basic arithmetic operations:

* "fused multiply-add" could just be called "multiply-add" because
  at Level 1, there is no rounding.

* Similarly, "exact dot product" should just be called "dot product".

But why is the dot product included in the basic arithmetic operations?
I don't see it as important as +, -, *, /. And not more important than
recip, sqr, case, pown, abs, and perhaps some other operations.
