Halloechen!
I try to use calc 2.02f for HMS (hour--minute--second) values. I
want to to convert them to decimal format. So far, I've typed S-I-S
(sine--inverse sine) which works, but isn't there a more
straightforward solution?
In particular, is there a possibility for this conversion in quick
calc mode (M-# q)?
Tschoe,
Torsten.

Hi Torsten,
I some time ago I played a bit with calc - and found out, how I
can call the calc functions from elisp:
(progn
(calc-eval "3x=9y" 'push)
(calc-solve-for "x")
(calc-eval 1 'top)) ; => x = 3 y
(progn
(calc-eval "3x^2+x+1=9" 'push)
(calc-poly-roots "x")
(calc-eval 1 'top)) ; => [1.47480963363, -1.80814296697]
Perhaps you can do something similar for your HMS problem
Stefan.
