hi, i can’t solve the last javascript project because the decimal numbers are incorrect…

```auto
//for example:
console.log(0.03 + 0.253)
//output = 0.28300000000000003

```

I am guessing that you are doing the cash register project.

I would either use on integer number of cents or look at the toFixed method.
