Sass 和四舍五入数字.这个可以配置吗? [英] Sass and rounding down numbers. Can this be configured?

问题描述

我有什么办法可以修改 Sass 处理小数位的方式吗?看到有几个人说Sass会动态做响应式布局所需的(target/parent)*100计算，并在编译时输出结果.它甚至还有一个百分比函数，它基本上会取两个值并执行此操作.

Is there any way for me to modify the way that Sass will handle decimal places? I saw a few people saying that Sass will dynamically do the (target/parent)*100 calculation needed for responsive layouts, and output the result at compile time. It even has a percentage function, which will essentially take the two values and do this.

唉，Sass 只会给我 3 位小数.到目前为止，我的理解是，在某些情况下，这可能不足以让所有浏览器正确显示布局而不会出现任何问题.

Alas, Sass will only ever give me 3 decimal places. My understanding up to this point has been that in some cases, this may not be a sufficient degree of accuracy for all browsers to properly display the layout without any hiccups.

谁能帮我弄明白这件事的真相?

Can anyone help me get to the bottom of this?

编辑

解决了.如果其他人感兴趣，我设法在 Sass 的 number.rb 中完成了我想要的，改变了 @precision 的值.这改变了所有浮点数的输出方式.

Solved. Incase anyone else is interested, I managed to accomplish what I wanted in Sass's number.rb, changing the value of @precision. This alters the way all floats are output.

推荐答案

如果您使用 Compass，您可以轻松地在项目文件 (config.rb) 中指定精度，而无需破解核心:

If you are using Compass, you can easily specify the precision in your project file (config.rb) without hacking the core:

Sass::Script::Number.precision = 8
