The method
round to the nearest multiple of the chosen place
Rounding, flooring and truncating differ
Rounding goes to whichever multiple is closer. Floor always goes down and ceiling always goes up — including for negatives, where floor(−2.3) is −3, not −2. Truncating just discards digits, so it rounds towards zero and behaves differently from floor on negative numbers.
