# Test not passing desipte exat same text?

Tell us what’s happening:
Hey! Working on Cash Register. Sorry for the really convoluted answer design, def not my best work. It was one of those things where I was getting a bunch of errors because of float rounding and it led me to create this monstrosity. As of now, I’m almost positive test 3 isn’t passing because of some similar float issue. Any idea whats going on with the pennies??

``````change = Math.round(change * 100)/100
``````

To the loop for pennies and it worked. A little head scratching as to why, but ill take it!

Your code so far

``````

let change = cash - price;

change: cid};
}else if(change > funds(cid)){
return {status: "INSUFFICIENT_FUNDS",
change: []};
}else{
let numHun = 0;
while(change >= 100 && cid[8][1] > 0){
change -= 100;
cid[8][1] -= 100;
numHun += 100;

out.push(["ONE HUNDRED", numHun]);
