”四捨五入” 的說法是用 round 這個動詞
這種行為則叫 rounding
要叫人家把一個數字四捨五入的話, 就是用 round it / round the number 這樣的說法
如果要指定把一個數字四捨五入為十位數或百位數
叫做 round it / round the number to the nearest ten / hundred
比如 123 如果是十位數為基礎則四捨五入後會是 120
但若以百位數為基礎則會是 100
把一個含有小數的數字四捨五入到整數, 叫 round it to the nearest whole number
到小數點後一位則是 round it to the nearest tenth
後兩位則是 round it to the nearest hundredth, 以此類推
把一個數字做 ”四捨” 叫 round it down
”五入” 則是 round it up
