This code ^^

Returns this vv

width = 1000  
selImg.width = 255  
height = 1000  
selImg.height = 255  
((width / selImg.width) \* selImg.height) = 900  
((height / selImg.height) \* selImg.width) = 900

Obviously somethings going wrong with the math as 1000/255\*255 should result in 1000.

How do I fix this?

(I have console results but I can only use one image in each post)

Keep in mind that `int` values can only hold whole numbers.

So this:

```auto
int x = 3 / 2;
println(x);

```

Will print out `1` instead of `1.5`.

You can fix this by converting one of the numbers to `float` first:

```auto
float x = float(3) / 2;
println(x);

```

By the way, instead of posting an image of your output, please try to paste a [MCVE](https://stackoverflow.com/help/mcve) directly in your message. You should also try breaking your calculations down into multiple lines to understand what’s going on better.
