Tell us what’s happening:
I’m working on Cash Register project and managed to write a complete code.
It works as expected except one condition which is:
checkCashRegister(3.26, 100, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]]) should return {status: "OPEN", change: [["TWENTY", 60], ["TEN", 20], ["FIVE", 15], ["ONE", 1], ["QUARTER", 0.5], ["DIME", 0.2], ["PENNY", 0.04]]} .
I tried to console.log the problem and noticed that for some reason
if(cashInDrawerValue > baseChange)
is validated as false in this case and I have no idea why.
Any help will be appreciated. Thanks in advance.
Your code so far
function checkCashRegister(price, cash, cid) {
// Variables
var change = cash - price
var baseChange = (cash - price).toFixed(2);
var cashInDrawer = cid.reverse();
var cashInDrawerValue = 0;
var changeRegister = [];
var changeRegisterValue = 0;
// Functions
var sumCashRegisterValue = function(arr) {
var value = 0;
for(var i = 0; i < arr.length; i++) {
if(arr[i][0] !== undefined) {
value += arr[i][1];
}
}
return value.toFixed(2);
}
cashInDrawerValue = sumCashRegisterValue(cashInDrawer);
// Find change
if(cashInDrawerValue > baseChange) {
for(var i = 0; i < cashInDrawer.length; i++) {
if(cashInDrawer[i][0] === "ONE HUNDRED" && change >= 100 && change <= cashInDrawer[i][1]) {
changeRegister.push(["ONE HUNDRED", change - change % 100]);
change = change % 100;
}
if(cashInDrawer[i][0] === "TWENTY" && change >= 20 && change <= cashInDrawer[i][1]) {
changeRegister.push(["TWENTY", change - change % 20]);
change = change % 20;
}
if(cashInDrawer[i][0] === "TEN" && change >= 10 && change <= cashInDrawer[i][1]) {
changeRegister.push(["TEN", change - change % 10]);
change = change % 10;
}
if(cashInDrawer[i][0] === "ONE" && change >= 1 && change <= cashInDrawer[i][1]) {
changeRegister.push(["ONE", change - change % 1]);
change = change % 1;
}
if(cashInDrawer[i][0] === "QUARTER" && change >= 0.25 && change <= cashInDrawer[i][1]) {
changeRegister.push(["QUARTER", change - change % 0.25]);
change = (change % 0.25).toFixed(2);
}
if(cashInDrawer[i][0] === "DIME" && change >= 0.1 && change <= cashInDrawer[i][1]) {
changeRegister.push(["DIME", change - change % 0.1]);
change = (change % 0.1).toFixed(2);
}
if(cashInDrawer[i][0] === "NICKEL" && change >= 0.05 && change <= cashInDrawer[i][1]) {
changeRegister.push(["NICKEL", change - change % 0.05]);
change = (change % 0.05).toFixed(2);
}
if(cashInDrawer[i][0] === "PENNY" && change >= 0.01 && change <= cashInDrawer[i][1]) {
changeRegister.push(["PENNY", change - change % 0.01]);
change = (change % 0.01).toFixed(2);
}
}
}
changeRegisterValue = sumCashRegisterValue(changeRegister);
if(baseChange == cashInDrawerValue) {
return {status: "CLOSED", change: cashInDrawer.reverse()};
}
if(baseChange == changeRegisterValue) {
return {status: "OPEN", change: changeRegister};
}
return {status: "INSUFFICIENT_FUNDS", change: []};
}
//console.log(checkCashRegister(3.26, 100, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]]));
