My data contains a column of room numbers. Each room number's first 2 digits is the floor number where the room is located. The =LEFT function works well for data that does not start with zero. The =LEFT function doesn't work well for data that starts with zero.

How can I get the formula to not ignore the first number when it is zero?

```
Room Number Formula Floor Number
1214 =LEFT (A2, 2) 12
2354 =LEFT (A2, 2) 23
1876 =LEFT (A2, 2) 18
1567 =LEFT (A2, 2) 15
0403 =LEFT (A2, 2) 40* (should be level 04)
1918 =LEFT (A2, 2) 19
0910 =LEFT (A2, 2) 91* (should be level 09)
```
