# var x = 100 + 100 - 5 * 2 / 3 % 7, result given is 197. So Remainder truncates result?

The example given in this lesson is var x = 100 + 100 - 5 * 2 / 3 % 7 and the result given is 197.

So I guess that means that the Remainder function truncates the result? Otherwise, it would be 196.6666...

You are working with the Int data type, so if you pull up playgrounds, you'll see that if you calculate 10 / 3 you won't get any decimal values. The result will be 3.

If you input 10.0 / 3.0 you will get a different result, 1.428571428571429, as Swift will infer a double data type.

Modulo (%) is only available for Int data type. You need to use the remainder method for Doubles and Floats.
