Hi -- I'm fiddling with NumPy's chopping and truncating operators: round, fix, ceil, and floor. In the case where they are passed real args, they work just fine. However, I find that when they are passed complex args, I get the following:
round -> works fine. ceil -> throws exception: 'complex' object has no attribute 'ceil' floor -> throws exception: 'complex' object has no attribute 'floor' fix -> throws exception: 'complex' object has no attribute 'floor' Please see the session log below for more details. My question: Is this a bug or a feature? It seems to me that if you implement round for complex args, then you need to also support ceil, floor, and fix for complex args, so it's a bug. But I thought I'd ask the developers what they thought before filing a ticket.
