Tell us what’s happening:
My code works, but the FCC tests don’t accept it. I believe it’s an error on your side. How can this be fixed? I ran all the tests manually changing the price, cid and cash values and it’s all perfect. I did use the search bar and there are apparently other people who got this issue but unfortunately I do not understand what the solution was. First, I thought it’s because I was working with integers as cents so I adapted it to use floats but STILL it doesn’t pass, while manually it’s all flawless.
This is my JS:
let price = 11.95;
let actualPrice = Math.round(price * 100);
let cid = [
["PENNY", 1.01],
["NICKEL", 2.05],
["DIME", 3.10],
["QUARTER", 4.25],
["ONE", 90.00],
["FIVE", 55.00],
["TEN", 20.00],
["TWENTY", 80.00],
["ONE HUNDRED", 200.00]
];
let actualCid = cid.map(([name, value]) => [name, Math.round(value * 100)]);
console.log(actualCid);
let due = [
["PENNY", 0],
["NICKEL", 0],
["DIME", 0],
["QUARTER", 0],
["ONE", 0],
["FIVE", 0],
["TEN", 0],
["TWENTY", 0],
["ONE HUNDRED", 0]
];
