I am referring to the HP-21 Woodstock calc...Thanks.

ive only got the cce emulators

classics come up with 7.968420280E95
HP21 7.9683417E95
HP65 7.968420280E95
HP67 7.968419661E95
HP31E 7,968419E95

Different families, different algorithms I suppose

Running on some actual calculators:

HP29C -- 7.968419661 E95
HP15C -- 7.968419664 E95
HP33s -- 7.96841966626 E95
HP50g -- 7.96841966626 E95 (for ' 3. 201 y^x ')
HP50g -- 79684196662762430801634396.... (for ' 3 201 y^x ' in exact mode)

Biggest question is how I ended up with so many calculators!
