将BTC jQuery计算器解析为美元

Question

我在javascript/jquery中有这个投资计算器。它根据特定计划计算某人将获得的利润。它被写成与比特币值一起工作，就像这样0.36000000 BTC。我只需要将其解析为3,6格式。

jQuery(function($){
    //Setting calculator
    var percent     = [0.36,0.46,0.52];
    var minMoney    = [0.001,5.001, 10.001];
    var maxMoney    = [5,10,99999999.9999];
    $("#btc_amt").val(minMoney[0]);
    /*calculator*/
    function calc(){
        money = parseFloat($("#btc_amt").val());
        id = -1;
        var length = percent.length;
        var i = 0;
        do {
            if(minMoney[i] <= money && money <= maxMoney[i]){
                id = i;
                i = i + length;
            }
            i++
        }
        while(i < length)
        if(id != -1){
            profitHourly = money / 100 * percent[id];
            profitHourly = profitHourly.toFixed(8);
            profitDaily = profitHourly * 24;
            profitDaily = profitDaily.toFixed(8);
            profitWeekly = profitDaily * 7;
            profitWeekly = profitWeekly.toFixed(8);
            profitMonthly = profitDaily * 30;
            profitMonthly = profitMonthly.toFixed(8);

            if(money < minMoney[id] || isNaN(money) == true){

Answer 1

让它工作了，谢谢。刚刚更改了toFixed(n)的数量

Answer 2

 $.getJSON( "https://api.coindesk.com/v1/bpi/currentprice/usd.json", 
    function( data) {
    var amountInBtc = 0.005; //convert 0.005 btc to usd
    var exchangeRate = parseInt(data.bpi.USD.rate_float);
    var amount = amountInBtc * exchangeRate;
    console.log(amount);
    });
