Значения в массиве анализируются как строка вместо dec

---

В настоящее время я работаю над упражнением алгоритма в лагере свободного кода, но столкнулся с проблемой с этим конкретным упражнением: https://www.freecodecamp.org/challenges/exact-change

Функция принимает несколько параметров и возвращает почти правильные значения.

checkCashRegister(3.26, 100.00, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.10], ["QUARTER", 4.25], ["ONE", 90.00], ["FIVE", 55.00], ["TEN", 20.00], ["TWENTY", 60.00], ["ONE HUNDRED", 100.00]]);

Мой код возвращает массив с правильными значениями, но десятичные дроби анализируются как строки.

[ [ 'PENNY', '0.04' ],
  [ 'NICKEL', 0 ],
  [ 'DIME', '0.20' ],
  [ 'QUARTER', '0.50' ],
  [ 'ONE', '1.00' ],
  [ 'FIVE', '15.00' ],
  [ 'TEN', '20.00' ],
  [ 'TWENTY', '60.00' ],
  [ 'ONE HUNDRED', 0 ] ]

Есть идеи, где я ошибаюсь? , Я пытался отладить это в течение многих лет, но не могу найти изъян.
мой код:

function checkCashRegister(price, cash, cid) {
	var moneyValues = [[0.01],[0.05],[0.10],[0.25],[1],[5],[10],[20],[100]];
	var outPutChange = [["PENNY", 0], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0.00], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]];
	var allCashInReg =0;
	var final =[];	


	console.log(cid);
	//sum all cash in register
	for(var a=0; a<cid.length;a++){
		allCashInReg+= cid[a][1];
	}
	console.log("All Available Cash in register is: €"+allCashInReg.toFixed(2));
	var changeDue = (Math.abs(price - cash)).toFixed(2);//calculate to 2 decimal places	
	console.log("Change due  is: €"+changeDue);


	//if change due is the same as all cash in register
	if(allCashInReg==changeDue){
		console.log("Closed");
		return "Closed";
	}
	//if change due is more than all cash in register
	else if(allCashInReg<changeDue){
		console.log("Insufficient funds");
		return "Insufficient Funds";
	}
	//else run the script	
	else{
					var k = moneyValues.length;
					while(k>=0){				
						//if the change due divided by the money value is >0
						if((changeDue/moneyValues[k])>=0){
							var denomination = moneyValues[k];//denomination being used
							var cashRegVal = cid[k][1];
							console.log("\nChecking: €"+ denomination+".....");
							var divider = Math.floor(changeDue/moneyValues[k]);// the number of times the denomination fit into the change due.Rounded down 					
							
							if(divider!=0){											
									var divider2=0;
									//set the divider value used to calculate the transactions
									if(changeDue>cashRegVal){
										divider2 = cashRegVal/denomination;
										console.log("Divider value is:"+divider2);
									}
									else {
										divider2 = Math.floor(changeDue/denomination);
										console.log("Divider value is:"+divider2);
									}

									
									var valueToDeduct = parseFloat(denomination*divider2).toFixed(2);
									console.log("Change due is: €"+changeDue);
									console.log("Amount of "+cid[k][0]+"(\'s') in cash register: €"+cashRegVal);
									console.log("Value to deduct: €"+valueToDeduct);
									if(cashRegVal>=valueToDeduct){									
										//Update the value in the cash register
										cashRegVal=cashRegVal-valueToDeduct;
										console.log("Valid transaction!\n");								
										console.log("New amount of "+cid[k][0]+"(\'s) in cash register: €"+cashRegVal);
										changeDue = (changeDue - valueToDeduct).toFixed(2);
										console.log(divider2+" "+cid[k][0]+'(\'s) have been deducted from the Cash Register');
										console.log("Change due is: €"+changeDue);	
										//parse value as float and put into the array	
															
										outPutChange[k][1]=parseFloat(valueToDeduct).toFixed(2);																					
									}

									else{//if not enough of denomination in cash register
										console.log("Insufficient funds\n");
										return ("Insufficient Funds");
									}
							}
							else{//if denomination too big to use for change
								console.log("Too big to use\n");								
							}													
						}//end of if				
						k--;						
					}//end of while
		}//end of else




			
			//final check on change given
			if(changeDue>0){
				console.log("Insufficient funds")
				return "Insufficient Funds";
			}
			else{
		    console.log("\nTransaction Complete! \nHere is a list of your change:\n ");

			console.log(outPutChange);//print the change					
			return outPutChange.reverse();		
			}
			
		//end of checkchange function		
}//end of function

Что я уже пробовал:

Он отладку кода,обработку выходных значений
