and if I said `oi = PI/2` it does work …

thank you

Hi mloiz,

It is because of the way operation works.

Here you are dividing 2 integers so the result will also be an integer (even if you are storing it in a float).  
More precisely 1/2 = 0.5 so you get 0.

Now with PI/2, you divide a float with an integer so you will get a float (to keep the maximum precision).

To solve your problem, try doing this:

```auto
1/2.0

```

By doing that, you are saying my divisor is a float number so divide an integer by a float.

Integer division is a common confusion when learning Processing – or Java.

There is also dedicated question for it on the wiki troubleshooting page:

- **[Why does 2 / 5 = 0 instead of 0.4?](https://github.com/processing/processing/wiki/Troubleshooting#why-does-2--5--0-instead-of-04)**
