How do i say rounding up, or rounding down?

For example if I round 75.6 up, it goes to 76. If I round 75.4 down, it goes to 75.

- rounding up, rounding down = 반올림(하다)

- rounding up, rounding down = 반올림(하다)

(예문)12.3을 반올림하면 12이고, 15.9를 반올림하면 16이다.

'사사오입'이라는 말은 거의 안 써요. 저도 사사오입이라는 말은 한번도 써본적이 없어요 ^^ --Jay shin 02:13, 20 October 2009 (UTC)
