I have run into an error. I am using https://developer.paypal.com/docs/checkout/integrate/ to implement the PayPal payment into my ASP.NET MVC Project. My currency is a float, and the project has prices like 150,99. Whenever this price goes through, it will say that the price is 99,00 EUR. It only reads what is behind the comma. Whenever the price is 190,00, it will correctly say that the price is 190,00 EUR. How do I fix this?

The JavaScript on the front-end is currently this:

<script>

    var totalPrice = (@ViewBag.totalPrice);

</script>

<script src="https://www.paypalobjects.com/api/checkout.js"></script>

<script>

    // Render the PayPal button

    paypal.Button.render({

        // Set your environment

        env: 'sandbox', // sandbox | production



        // Specify the style of the button

        style: {

            layout: 'horizontal',  // horizontal | vertical

            size: 'large',    // medium | large | responsive

            shape: 'pill',      // pill | rect

            color: 'black'       // gold | blue | silver | white | black

        },



        // Specify allowed and disallowed funding sources

        //

        // Options:

        // - paypal.FUNDING.CARD

        // - paypal.FUNDING.CREDIT

        // - paypal.FUNDING.ELV

        funding: {

            allowed: [

                paypal.FUNDING.CARD,

                paypal.FUNDING.CREDIT

            ],

            disallowed: 

        },



        // Enable Pay Now checkout flow (optional)

        commit: true,



        // PayPal Client IDs - replace with your own

        // Create a PayPal app: https://developer.paypal.com/developer/applications/create

        client: {

            sandbox: '<removed>',

            production: '<insert production client id>'

        },



        payment: function (data, actions) {

            return actions.payment.create({

                payment: {

                    transactions: [

                        {

                            amount: {

                                total: totalPrice,

                                currency: 'EUR'

                            }

                        }

                    ]

                }

            });

        },



        onAuthorize: function (data, actions) {

            return actions.payment.execute()

                .then(function () {

                    window.alert('Payment Complete!');

                });

        }

    }, '#paypal-button-container');

</script>

And back-end for the price is like this:

        [HttpGet]

        public IActionResult Index()

        {

            ...

            float totalPrice = 0;

            float sendcost = 2.95f;

            ...

                        foreach(ShoppingCartModel item in model)

                        {

                            item.subtotal = item.qty * item.price;

                            totalPrice += item.subtotal;

                        }

                        if(totalPrice < 100)

                        {

                            ViewBag.totalPrice = totalPrice + sendcost;;

                        }

                        else

                        {

                            ViewBag.totalPrice = totalPrice;

                        }

                    }

                }

                ...

        }

The official answer is that your web app's language setting causes the server to output numerical values with a comma as decimal separator. So

var totalPrice = (@ViewBag.totalPrice);

ends up

var totalPrice = (150,99);

in the browser and since JavaScript has something called a comma operator, totalPrice is now 99.

To fix this on the server side, you can change the locale used for formatting to English by adding

CultureInfo.DefaultThreadCurrentCulture = CultureInfo.GetCultureInfo("en-US");

to the Configure() method in Startup.cs.
