# Unexpected floating problem in loop

Tell us what’s happening:
I stuck in the final project .
in the loop below initial setup I’m getting unexpected results
first iteration is fine 96.74- 20 =76.74
in second iteration 76.74-20 =56.99999999995
the same happens in console.log speratly i.e. ( console.log(76.74-20) )

``````function checkCashRegister(price, cash, cid) {
var change = cash - price;
var register = [0.01, 0.05, 0.10, 0.25, 1.00, 5.00, 10.00, 20.00, 100.00];
var count = []
for(let i=0;i<register.length;i++){
count.push(Math.floor(cid[i][1]/register[i]))
}

console.log(change).  //here it's 96.74
for(let i = register.length-1;i>=7;i--){
if(  (change/register[i]) > 1 ){
let temp = count[i]
while(temp !== 0){
change -= (register[i])
console.log(change). //first iteration 76.74 ,second 56.999999999995
temp--
}
}
}
console.log(96.74-20) // 76.74
//console.log(76.74 - 20) // 56.999999995
// count array[ 101, 40, 31, 17, 90, 11, 2, 3, 1 ]
//console.log('change'+change)

//console.log(' CID '+cid)

var output = { status: null, change: [] };
var total = cid.reduce((sum,current) =>  sum+current[1],0)
if(total === change)
{
output.status = 'CLOSED'
output.change = cid
return output
}
if(total < change)
{
output.status = 'INSUFFICIENT_FUNDS'
return output
}
if(total>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]]))

Challenge: Cash Register

What can you do to avoid floating point with all your values in `register` array?
