Comment #5 on issue 2418 by [email protected]: Interval.evalf() returns
a mpmath interval
http://code.google.com/p/sympy/issues/detail?id=2418
I am trying to fix this issue, and wanted some more input:
1. I have removed the interval_evalf() functions from inequalities.py and
all tests for that file pass.
2. I have also added a method Interval.to_mpmath(self, prec) to sets.py ,
that has the following code:
return Interval(self.left._to_mpmath(prec), self.right._to_mpmath(prec),
left_open=self.left_open, right_open=self.right_open);
or should this just be
return [ self.left._to_mpmath(prec), self.right._to_mpmath(prec)]
Will include tests based on the choice above.
3. For the evalf(), the Interval._eval_evalf() seems to be already doing
what
was intended in Comment 1, and is returning a type
<sympy.core.sets.Interval>. Does this still need to change?
