Question

I have the following strings in JavaScript as examples:

-77.230202
39.90234
-1.2352

I want to ge the first two digits, before the decimal. While maintaining the negative value. So the first one would be ‘-77’ and the last would be ‘-1’

Any help would be awesome!

Thank you.

Answer 1

You can simply use parseInt().

var num = parseInt('-77.230202', 10);
alert(num);

Note: parseInt() can return NaN, so you may want to add code to check the return value.
