NodeJS: Convert string X,XXX.XX to float

I'm bothering you because I'm looking to convert a string into a float with node.JS. I have a string that comes back from a request and looks like: x,xxx.xxxx (ex. 4,530.1200) and I'd like to convert it to a float: xxxx.xxxx (or 4530.1200). I've tried to use: parseFloat(str) but it returns 4. I also found Float.valueOf(str) on the web but I get a ReferenceError: Float is not defined error.

Solution

  • You can use string replace to solve this kind of problem.

    str = '4,530.1200';
parseFloat(str.replace(/,/g, ''));

    This will remove all the , from your string so that you can convert it to the float using parseFloat.

    Notice the g flag in regex, it represents global, by using this you are specifying to remove all the matched regex.
