(Js) number method to add a comma after the first number and remove the 2 number after comma ?? is there any?

Question

I want to format a number to two decimal places. Say the user enters 8764444 it should be formatted as 8.76. is there some built-in function in javascript to do that?

Answer 1

No, there is no built in method for exactly that, but you can use the substr method to get parts of a string to do the formatting:

var input = "8764444";

input = input.substr(0, 1) + '.' + input.substr(1, 2);

// show result in Stackoverflow snippet
document.write(input);
