Comparing negative numbers in javascript
提问by Tom G
I'm sure this is a simple problem, but I'm comparing negative numbers in javascript i.e.:
我确定这是一个简单的问题，但我正在比较 javascript 中的负数，即：
var num1 = -83.778;
var num2 = -83.356;
if(num1 < num2)
{
// Take action 1
}
else
{
// Take action 2
}
This script will always take action 2, even though num1is less than num2. Whats going on here?
此脚本将始终执行操作 2，即使num1小于num2. 这里发生了什么？

How does if (parseFloat(num1) < parseFloat(num2))work? Maybe you're numbers are turning into strings somewhere.
如何if (parseFloat(num1) < parseFloat(num2))工作？也许你的数字在某个地方变成了字符串。
