Re: Where is the correct round() method?

[pigmartian]

it could be that 3.0 is using "banker's rounding" --- rounding to the 
even digit.  the idea behind it behind it being to reduce error 
accumulation when working with large sets of values.

Works for me on Python 2.5 on Linux running on "Intel(R) Core(TM)2 Duo 
CPU".  What system are you on?


It could be that 2.5 is really 2.49999... which would round down to 2, 
but on any modern CPU (using IEEE floating point), 2.5 should be 
representable exactly.
