Javascript convert number

Question

For instance I have this number: 1.000,20 I want to convert it to 1000.20 or just remove everything behind the comma like this: 1000.

How do I achieve this? I did this:

console.log(num3.replace(/\[,.]/g, ''), 'test', num3.replace(/\,/g, ''));

Which results in: 0,00

Here is a Fiddle which console.logs the output on line 18 in the JS: https://jsfiddle.net/kn7ae9e2/1/

When you say "I have a number", I guess what you mean is "I have a string"?? Also, converting "1.000,20" --> "1000" is not only removing after the comma, you have also removed the ".". Is that also desired/intentional? Do you want the final result to be a string or a number? Please be very specific in what you are asking; this is too vague and open to interpretation. — Tom Lord

You can replace the . first and then match everything before ,

"1.000,20".replace(/\./g, "").match(/\d+(?=,)/) //prints 1000

Demo

var output = "1.000,20".replace(/\./g, "").match(/\d+(?=,)/) //prints 1000
console.log( output );

This results: null it is indeed a string like tomLord mentions above than I tried this: Number(num3.replace(/\./g, "").match(/\d+(?=,)/g)) but this results in 0

You can split the string and recombine it like so:

num3="1.000,20";
num3.split(',')[0].split('.').join('') //"1000"

You can prepend it with the unary + operator to typecast it to a number

+num3.split(',')[0].split('.').join('') ///1000

If you want to preserve the value after the decimal point, you can do something like this:

function parseNumber(str){
    var splits = str.split(',');
    var preDec = splits[0].split('.').join('');
    return splits.length > 1? +(preDec+'.'+splits[1]): +preDec;
}

parseNumber("1.000,20"); //1000.2
