How can I round a number in Javascript tofixed returns a string?

Question

Below is my code implementation:

var someNumber = 123.456;

someNumber = someNumber.toFixed(2);

alert(typeof(someNumber));

//alerts string

The toFixed() method returns a string but I want to round the number to 2 decimal places. Can anyone tell me how to do it?

Answer 1

You get a string because 0.1 and powers are not representable in binary floating-point systems. So to trim it to the exact precision required for display, outputting it as a string is the only solution.
