They're not really conversion "routines" per se, George. As noted in other
messages, these casios are not programmable. It's really just a D.M.S. key
that we're talking about. So, for example, you could enter -20, press DMS (it's
labeled symbolically), then enter 30, press DMS again, and finally enter 15, and
press DMS again. The calculator displays -20'30'15' and internally it's
represented as
-20.50416667. No big deal. Any trig calculator should do that and most do,
but the implementation is very nice on the casio fx-2** series, even
improved on the latest models. And it costs $8 or less and lasts forever.
By the way, if any word in the above post is considered an insult by any

punishment. :-)
