n roundTo: 3. ==> 3 2 roundTo: n ==> 2.12435454313

Am I doing something wrong?

#roundTo: rounds to the closest multiple of its argument. Appears to work fine in the examples you gave.

Perhaps you meant this:

2.12435454313 roundTo: 0.001 ==> 2.124

Be aware that this might print as 2.124000000000001 for certain numbers. If you really want 3 decimal places, use:

2.12435454313 printShowingMaxDecimalPlaces: 3 ==> '2.124'

or:

2.12435454313 printShowingDecimalPlaces: 3 ==> '2.124'
