Misc · Numbers: a result goes on whole; long readings wrap

A calculator result stays in the sum as `a`, handed to evaluate with
its whole value, so 1 ÷ 3 = × 3 = gives 1; sign turns it and delete
takes it. Equals waits on a dangling operator. The converter's reading
wraps in its box rather than ending in an ellipsis, and tests hold
Control, the = key, a point after a result and the six digits.
