In this exercise, we want to check if x is an integer. So my idea is to first create a variable y that is equal to x rounded. Example: x=5.6 => y=5.0

But up to now, I think I haven't seen a function that does that, so how am I supposed to do that?

```
def is_int(x):
#I first want to create a variable y that is x rounded
y=
if x-y == 0:
return True
else:
return False
```

Can someone tell me if I am trying to do the right thing here? And if maybe I missed that function in the previous lessons...

Thanks in advance
