{{x | number:'1.1-3'}}
(15).toFixed(2) //15.00

Javascript Method Chaining: Correct method chain toFixed() and parseFloat() to return a number, not a string?

Hope this helps toFixed is a method of Number and returns a string. window.parseFloat is a global function and not a method of String, but if you really must, then you can make it a String method, otherwise just use it as a function. You can even use the unary plus operator in this case.
(There is a great deal of discussion about augmenting native objects that I am not going to go into, you can do some research and make up your own mind.)
if (!String.prototype.parseFloat) {
    String.prototype.parseFloat = function () {
        return parseFloat(this);
    }
}

var lat = 123.456789;

console.log(parseFloat(lat.toFixed(2)));
console.log(lat.toFixed(2).parseFloat());
console.log(+lat.toFixed(2));
123.46
123.46 
123.46 

Javascript parseFloat changes number

this one helps. Both numbers have the same floating point representation, because floating point numbers are only accurate to a certain level.
If these numbers are for calculation, why do you need to convert them with better than 1 in a quadrillion precision? If these values are not for calculation, leave them as strings.

Javascript parseFloat(number) - parseFloat(number2) returning int

this one helps. This looks like a locale problem: parseFloat only recognizes a period as a decimal point; it stops parsing when it gets to the comma, giving you only integer values. Unfortunately, there is no way to change this behavior. You need to replace the commas with periods in your number strings in order to get a decimal number.

parseFloat return NaN javascript number

fixed the issue. Will look into that further I don't see you using z1 in your calculations anywhere. Furthermore, $(this).text() should always be empty since td.priceCash doesn't have any text inside of it.
Perhaps you really meant to do this?
    $("#cashAmount"+counterCash).keydown(function () {
            setTimeout(function () {
              var sum3 = 0;
                $('.priceCash').each(function(i,el) {
                    sum3 += parseFloat($("input",this).val());
                });

Javascript why Number and ParseFloat both create a long number when adding up numbers?

I think the issue was by ths following , try this solution JSFiddle link:
$(document).on('click','.btn',function(e){
    var price = $(this).attr('data-price');
    var curPrice = localStorage.getItem('totalPrice');
    var setPrice = Number(price) + Number(curPrice);
    alert(Math.round(setPrice * 100) / 100);
});
