RE: Extending the precision of Woodstock or Saturn based calculators
Oddly enough, I was looking at extended precision math just the other week - on a Z80.
Extended precision data was held in data registers, and the number of registers to use was the main variable (if set to zero, only the Stack registers are used).

I appreciate you guys are talking about CPU level instructions. I'm sill thinking about the higher levels (like how to display the result). Extending the precision by a single register should give proof of concept, check the new math routines, yet not slow down processing too much.

Start with divide by 3, and square root of 5, before jumping to : asin(acos(atan(sin(cos(tan(1/9))))))
