Comment(by was):
The reason this is *broken* is because the implementation of the method
_evalf_ in sage/symbolic/integration/integral.py in DefiniteIntegral
completely ignores the parent and the precision of a and b. This function
has to be rewritten to take into account the precision of the inputs:
{{{
def _evalf_(self, f, x, a, b, parent=None):
from sage.gsl.integration import numerical_integral
return numerical_integral(f, a, b)[0]
}}}
