Style options

Demo showing the 3 values for style. If style is set to currency, the currency option must also be set, as there is no default.

JavaScript

var largeNum = 100000000.150001;

console.log("Currency: " + 
            new Intl.NumberFormat("cs-CZ", {
                style: "currency",
                maximumFractionDigits: 2
            }).format(largeNum));
