RealDigits rounds sometimes

In Mathematica 5.01:

RealDigits[Pi,10,5] gives 3.1416

RealDigits[355/113,10,5] gives 3.1415

RealDigits[355./113,10,5] gives 3.1416

Earlier versions, Mathematica 4.1 and 4.2 never round as near as I can tell.

Can anyone tell me under what conditions I can expect rounding to occur, and can I stop
this behavior in 5.01?
