Rounding

数值修约

There are several rounding functions in the calculator. All of them have two parameters. The first parameter denotes the number to be rounded. The second parameter is optional and defines the number of decimal places for rounding. If the parameter is omitted, the number of decimal places is 0.

此计算器提供数个修约函数。所有函数都有两个参数。第一个参数表示要修约的数值。第二个参数为可选，用于定义修约的小数位数。如果此参数省略的话，默认小数位数为0。

roundUp \u2014 rounds the number up, i.e. far from the zero;

roundUp \u2014 向上修约，即远离零；

roundDown \u2014 rounds the number down, i.e. towards the zero;

roundDown \u2014 向下修约，即靠近零；

floor \u2014 rounds the number towards the minus infinity;

floor \u2014 向负无穷方向修约；

ceiling \u2014 rounds the number towards infinity.

ceiling \u2014 向正无穷方向修约。

decimalPart \u2014 removes the integer part of a number.

decimalPart \u2014 去除数字的整数部分。
