Duh. I should have said:
def __eq__(self, other):
if isinstance(other, FixedPoint):
xn, yn, p = _norm(self, other, FixedPoint=type(self))
return xn == yn
else:
return False
def __ne__(self, other):
if isinstance(other, FixedPoint):
xn, yn, p = _norm(self, other, FixedPoint=type(self))
return xn != yn
else:
return True
..using == and != instead of cmp(). I need to:
[] Stop working so late
[] Stop drinking so much Diet Coke
[] Stop putting so much rum in the Diet Coke
[] Go back to school ;)
