萨斯 |数值函数
就像 SASS字符串函数一样，SASS 提供了一组简单的函数来更改数值，并且这些值可以按照您希望的方式工作。请注意，可以为除“percentage()”之外的每个函数赋予 CSS 值描述符，例如“px”或“rem”。在这种情况下，SASS 将忽略这些单位，并且它们不会显示在结果中。
下表列出了 Sass 中的所有数值函数：
| Function | Description | Example |
|---|---|---|
| percentage(number) | This method converts a unitless number to the percentage. It means, multiplies it by 100. | percentage(2.5) Output: 250 percentage(4em) Output: syntax error |
| round(number) | This method rounds the number to the nearest whole number. | round(2.25) Output: 2 round(2.5) Output: 3 |
| ceil(number) | This method rounds the number up to the nearest whole number. | ceil(2.25) Output: 3 |
| floor(number) | This method rounds the number down to the nearest whole number. | floor(2.25) Output: 2 |
| abs(number) | This method returns the absolute value of the number. | abs(2) Output: 2 abs(-2) Output: 2 |
| min(numbers) | This method returns the smallest value in the list of numbers. | min(4, 5, -7, 8, 2) Output: -7 |
| max(numbers) | This method returns the largest value in the list of numbers. | max(4, 5, -7, 8, 2) Output: 8 |
| random() | This method returns a random number in the range of [0, 1]. | random() Output: 0.4965 |
| random(limit) | This method returns a random whole number in the range of [1, limit]. | random(4) Output: 2.4652 |
