New issue 2259 by [email protected]: nsimplify should use any symbols that
already appear in expr
http://code.google.com/p/sympy/issues/detail?id=2259
nsimplify will only use certain symbols in the returned expression if it is
told to. It seems to me that if there are NumberSymbols like pi already in
the expression, those at least should be used:
h[17] >>> nsimplify(pi/7.)
0.142857142857143*pi
If nsimplify looked to see that there was already a pi then the user
wouldn't have to explicitly say so:
h[17] >>> nsimplify(_, [pi])
pi/7
Should nsimplify check for such symbols if none are given?
