Summary: solve with floats results in loss of precision; evalf, too
Comment #1 on issue 3533 by [email protected]: solve with floats results in
loss of precision; evalf, too
http://code.google.com/p/sympy/issues/detail?id=3533
Hmm...it appears that even evalf has a problem with evaluating an
expression like the following:
expr
x - 100000*sqrt(2500000001) + 5000000001
_.n()
x
It should have returned x + 9.99999999800000e-11
