This is all very interesting ( and confusing (to me, maybe others) at the same time ...) ... Question 0: Are you sure this is not a bug ? >>> N.array([66]).round(-1) [60] >>> N.array([66.2]).round(-1) [ 70.] Question 1: Was this way of round already in Numeric and /or in numarray ? Question 2: Does this need to be better documented (complete and corrected(!) docstrings - maybe a dedicated wiki page ) !? This is related to "How does Matlab or IDL or others do rounding ?" - This would at least determine how many people would be surprised by this. (I would say that *if* Matlab rounds the same way, we might need less documentation ...)
