How to sort an array of floats in JavaScript?

Question

I tried below example but now working with correct information.

var fruits = [110.111, 1245.22222, 2.458, 0.001];
fruits.sort();
document.write(fruits);
         


        

Answer 1

Use Custom Function for sorting.

To sort it you need to create a comparator function taking two arguments and then call the sort function with that comparator function as follows:

fruits.sort(function(a,b) { return parseFloat(a) - parseFloat(b) } );

If you want to sort ascending change parseInt(a) - parseInt(b) and parseInt(b) - parseInt(a). Note the change from a to b.
