```

function addTwoDigits(n) {
var result;
result = Math.floor(n/10) + 10*(n/10-Math.floor(n/10));
console.log(result);
return result;

}
addTwoDigits(29);

``` the output was 10.9999999999999999999999999999999 I wonder why it was not 11 since according to normal way of calculation it should be rounded already but it's not. Is there any hidden computer science thoery behind this?

put Math.round()

function addTwoDigits(n) {
var result;
result = Math.floor(n/10) + 10*(n/10-Math.floor(n/10));
console.log(Math.round(result));
return result;

}
addTwoDigits(29);

Hope this helps.
