Comment #8 on issue 1321 by ondrej.certik: trigonometric functions of floating-point numbers should return floating-point numbers http://code.google.com/p/sympy/issues/detail?id=1321
What I meant is that 0.1 should be converted to Real first. We can discuss with what precision, I suggest the precision of the floats in python, which imho is machine precision. Then sin(Real(whatever)) should calculate with the precision of that Real. If it's 15 digits or 7 digits, that depends on the Real instance. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
