将变量舍入到X的下一个最接近的倍数 [英] Round a variable up to the next closest multiple of X

问题描述

我正在寻找一种方法将数字四舍五入到250的下一个最接近的倍数。例如，如果我有以下JS：

I'm looking for a way to round up a number to the next closest multiple of 250. So for example if I had the following JS:

var containerHeight = $("#container").height();

...我们想象containerHeight的价值是680px，我希望有办法最高为750px（如果值为1007，则应该最多为1250）。我怀疑这需要一个比我预期的更复杂的解决方案。或者jQuery有一个内置函数可以使这个可行吗？

...And we imagine the value of "containerHeight" was 680px, I would want a way to round up to 750px (if the value was 1007, it should round up to 1250). I suspect this requires a solution that is more complex than I anticipate. Or perhaps jQuery has a built in function that will make this feasible?

我想这更像是一个数学问题，而不是一个jQuery问题（但我的jQuery语法知识）也有点限制：）

I suppose this is more of a math question than it is a jQuery question (but my jQuery syntax knowledge is also a bit limited :)

非常感谢任何想法/帮助，
谢谢！

Any ideas / bits of help are greatly appreciated, Thanks!

推荐答案

containerHeight = Math.ceil(containerHeight / 250.0) * 250;
