Hello dear community
I need your help please, I am starting to doubt if I am good enough for this, 
but I do want to do it
I detected 2 errors
-
WHILE NOT WORKING:
when passing:
checkCashRegister(19.5, 20, [[“PENNY”, 1.01], [“NICKEL”, 2.05], [“DIME”, 3.1], [“QUARTER”, 4.25], [“ONE”, 90], [“FIVE”, 55], [“TEN”, 20], [“TWENTY”, 60], [“ONE HUNDRED”, 100]])
It seems the while is not looping under the same denomination but goes to the next and spoils the whole operations, I don’t understand why the while is failing -
MATH NOT ACCURATE:
when passing:
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]])
I still miss the exercise by 1 penny, meaning I don’t manage yet to make good mathYour code so far
