将弧度转换为度数的方法是什么? [英] What is the method for converting radians to degrees?

问题描述

我偶尔会遇到这种情况，但总是忘记怎么做.

I run into this occasionally and always forget how to do it.

那些经常出现的东西之一.

One of those things that pop up ever so often.

另外，以弧度表示的角度转换成度数然后再转换回来的公式是什么?

Also, what's the formula to convert angles expressed in radians to degrees and back again?

推荐答案

radians = degrees * (pi/180)

degrees = radians * (180/pi)

至于实现，主要问题是您希望 pi 值的精确程度.有一些相关的讨论这里

As for implementation, the main question is how precise you want to be about the value of pi. There is some related discussion here
