Status: Accepted Owner: ---- Labels: Type-Defect Priority-Medium New issue 1321 by [email protected]: trigonometric functions of floating-point numbers should return floating-point numbers http://code.google.com/p/sympy/issues/detail?id=1321
currently In [1]: cos(0.5) Out[1]: cos(0.500000000000000) In [2]: acos(0.5) Out[2]: acos(0.500000000000000) I find that behaviour ok when the argument is a fraction, but with a floating-point number it is more coherent to return a floating-point number. Plus, solve wouldn't give such useless answers; In [5]: solve(cos(x)-.5, x) Out[5]: [acos(0.500000000000000)] -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
