OK, there are a few occasions when the parallel function may be used for other mathematical applications, but IMvHO others would have made more sense. For instance functions that accurately evaluate √(1+x²) – 1, or in addition to ex–1 a general ax–1 function. Or 1–sin(x) and 1–cos(x). Or √(x²+y²).

I seem to remember there were a couple of vocal advocates for || being easily accessible. I didn't see the need for it but apparently it is a critical feature that makes any calculator without it useless. I saw no harm and Walter was the layout person.

Yes to your other suggestions for improving accuracy, I got in what I could -- limited flash space and running out of energy justifying everything.

Apart from 1 - sin(x) which doesn't have accuracy concerns that I can see and √(x²+y²) which is present already as complex ABS.
