I'm curious - can you elaborate on this? In C I am presuming you are using binary rather than decimal. When you mean IEEE754 do you mean floating point binary or decimal? I've always thought doing maths stuff in binary is a pain as we generally view the results in decimal, which makes it hard to determine accuracy in terms of the number of decimal points.

In keeping with the emulated HP-30b I guess. I suspect the HP-27s is similar to the HP-17b and onwards, but I wouldn't mind more data...

Exactly? That is a little disappointing.
