# If an integer ends with an 1.

I want to use an if statement to check whether a number ends with a one or not. These ints are whole numbers too. Can I check whether an int ends with an 1 or not? I don't want to round the number. Thank you in advance.

If you divide an integer by 10 the result will be the number of "10s" that exist within your value, but there may be some left over - the remainder. The remainder can be between 0 and 9. It will be 0 if the integer is evenly divisible by 10. As it turns out it will be 1 if the integer ends in a 1.

The modulus operator gives you the remainder after dividing one value by another, so you can use that operator to easily check if the remainder is 1...

```
if (value % 10 == 1)
{
Debug.Log(value);
}
```

All of the information you need to answer that is already there. What happens when you divide 2 by 10? You get 0 with a remainder of what? How about 22? 23? Do the math, then apply that to what I answered above.
