Comment #7 on issue 1321 by fabian.seoane: trigonometric functions of floating-point numbers should return floating-point numbers http://code.google.com/p/sympy/issues/detail?id=1321
I think we should use machine precision for the result, so the output of sin(0.1) would simply be In [1]: float(sin(0.1)) Out[1]: 0.0998334166468 anyway you can't set float's with more precision than machine precision, so I don't exactly see the reason to implement #3 (I see a utility of this for Real's, but not for float's) -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
