[New-bugs-announce] [issue10101] a bug in built-in function round() ?

[Retro]

New submission from Retro <vinetouu at gmail.com>:

>>> round(1.255, 2)
1.25

A bug in Python interpreter?


Shold have been:

>>> round(1.255, 2)
1.26

In mathematics, the .5 part is always rounded up, so in the example the .255 should be rounded to .26 so please fix this bug.
