jquery use of parseFloat and toFixed

This works :

var x = parseFloat($(this).val());
$(this).val(x.toFixed(2));

and not this :

$(this).val(parseFloat($(this).val())).toFixed(2);

I get "toFixed is not a function".

I don't understand why !

Another way to write this is with val(function)

$(this).val(function(_, currVal){
    return parseFloat(currVal).toFixed(2);
});

Your problem in second version is the chaining is incorrect

That is because you are applying toFixed on jQuery object and not the value. Just shift it inside one parenthesis.

$(this).val(parseFloat($(this).val()).toFixed(2));

Splitting up code to simpler and more understandable syntax is always a great idea though. Use a code minifier to take care of the build size.
