#roundTo: can be used for this (and is specified by ANSI Smalltalk, for those who care). If the screws only come in 16th inch increments, for instance, then "roundTo: 0.0625" will give you an exact result, since 16ths *are* exactly representable as floats.
OTOH, #round: (not in ANSI) appears to promise something that cannot be delivered for Floats, so is misleading, and it spreads the kind of confusion that resulted in this thread.
That's why I favor deprecating #round: for Floats. Regards, -Martin
