2016-05-21 18:10:06 +0200	asked a question	Why is sage behaving weird when rounding rational numbers? I might be doing something stupid, but Sage's `int()` and `round()` functions seem to be buggy to me. I'm trying to use these with rational numbers to round towards zero. I'd expect `-7/4` to round to `-1` and `+7/4` to round to `1`. Instead I get different behavior for rationals and their decimal representation: ┌────────────────────────────────────────────────────────────────────┐ │ SageMath Version 7.1, Release Date: 2016-03-20 │ │ Type "notebook()" for the browser-based notebook interface. │ │ Type "help()" for help. │ └────────────────────────────────────────────────────────────────────┘ sage: int(-1.75) # Correctly rounds towards zero -1 sage: int(-7/4) # Does not round towards zero -2 sage: (-7/4).round("toward") # Does not round towards zero (despite what the documentation claims!) -2 sage: -7/4 + 0.0 # The numbers are in fact the same! -1.75 How do I round rational numbers towards zero in Sage?
