Comment #12 on 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
I'm looking into this. My preliminary work is at
https://github.com/ness01/sympy or in short patch form at
http://pastebin.com/VxNTyqsx.
Still open problems are:
1) looking for "complex numbers with real coefficients" naively (cf lines
92 and 93) causes infinite recursion bugs
2) test test_floats in core/tests/test_match.py fails … but this is really
expected as far as I can tell
3) solve(cos(x)-0.5,x) returns "DomainError: there is no field associated
with RR", and I don't really understand why
Comments appreciated.
