mpmath... wow... just did what i needed :-)
Thanks, Mark! Hopefully i did not waste too much of your time... and
perhaps this discussion will send other lost sheeps in the right
direction.
(Still, it would make sense to have the goniometric functions in
decimal.)

Oh boy, now I will finally prove myself illiterate... well, so be it.
But i am after the extra precision:

food for thought. I know it's easy to complain about lack of
functionality, but it really was not my intention. Python is very cool
as it is and I still know too little about it to even suggest
anything. I just thought maybe I was

Hi Gabriel - than
Hi,
I have been looking for a Python module with math functions that would
both eat and spit Decimals. The standard math module eats Decimals
allright but spits floats... herefore exp(sin(Decimal())) produces exp
() of a float :-(
So far, i found:
