如何缩短返回的坐标？

Question

Using Cycript (mixed with javascript) via a tweak I have this code:

var latitude = [IS2Weather currentLatitude];

This returns -1.65456038607131e+25

I want to limit it to 6 decimal places (-1.654560), what is the correct way to achieve this please? I can't seem to get anything to work.

Answer 1

您是否尝试过调用latitude.toPrecision(6) ？

Answer 2

使用 javascript .toFixed(n)方法

latitude = latitude.toFixed(6);
