Comment #1 on issue 3019 by [email protected]: wrong result of
expression: 2**(1/2)=1
http://code.google.com/p/sympy/issues/detail?id=3019
The result is correct because 1/2 evaluates to 0, remember the integer
division here.
Btw, in plain python 2**(1/2) returns 1 too.
Use sqrt(2), root(2,2), 2**Rational(1,2), 2**(1/S(2)) or 2**(S(1)/2) for
the desired result.
