# How to get the remainder of 13/5 using KM?

It seems that it's a simple question but I don't know how to fix it after searching the wiki manual:Calculations [Keyboard Maestro Wiki]

13/5 = 2 and remainder is 3

How to get '2' and the remainder '3' using some formula in KM.

I don't know much about coding but I'm really want to learn something about it. Many thanks to any replay in advance Hi Alice,

I'm far from a math whiz, so offhand I can't think of a way to get both `2` and `3` from a single formula, but I can show you how to do so in two separate ones.

To get `2` from `13/5`, you can use the `TRUNC()` function in a calculation field (make sure to enclose the calculation whose result you want to truncate in parentheses inside the function, otherwise it won't be calculated before truncation):

`TRUNC((13/5))`

To get the remainder, `3`, you can use the `MOD` (short for "modulo") operator:

`13 MOD 5`

You can see the results for yourself in this sample macro, which uses the `%Calculate%` token to create a calculation field within a plain text field and enable these functions:

@gglick Thanks a lot!

And if you wanted to write a quotRem function (quotient and remainder) for `KM Execute ... Script actions`, you could do something like this:

Javascript

``````(() => {

// quotRem :: Int -> Int -> (Int, Int)
const quotRem = (m, n) => [Math.floor(m / n), m % n];

return quotRem(13, 5);

// --> [2, 3]
})();
``````

Applescript

``````-- quotRem :: Int -> Int -> (Int, Int)
on quotRem(m, n)
{m div n, m mod n}
end quotRem

on run

quotRem(13, 5)

--> {2, 3}

end run
``````
