[issue9885] Function Round does not work properly in some conditions

[paontis]

New submission from paontis <paoregs at gmail.com>:

For example round(10.3333, 1) returns 10.300000000000001 and round(1.3333, 2)returns 1.3300000000000001

I exect they return 10.3 and 1.33 rispectively

NOTE: other combinations work fine eg. round(10.3333, 2) or round(1.3333, 3)

See IDLE commands in the attached file round.txt

Used Python 2.6.6 for Windows
