An integer is just a number without a decimal part (for instance, `-17`

, `0`

, and `42`

are all integers, but `98.6`

is not).

For the purpose of this lesson, we’ll also say that **a number with a decimal part that is all 0s is also an integer**, such as `7.0`

.

This means that, for this lesson, you can’t just test the input to see if it’s of type `int`

.

If the difference between a number and that same number rounded is greater than zero, what does that say about that particular number?

### Instructions

**1.**

Define a function `is_int`

that takes a number `x`

as an input.

Have it `return True`

if the number is an integer (as defined above) and `False`

otherwise.

For example:

is_int(7.0) # True is_int(7.5) # False is_int(-1) # True
