Room Number Sorting
Because we allow characters and numbers as a room number, we have to sort by string. We can’t sort by number, as room A10, for example, is not a number. Room numbers will not display sequentially if the numbers are of different lengths. To ensure room numbers display sequentially, we recommend configuring the lower numbers with leading 0s. For example, if there are 10 floors, and the numbering is 101 for first floor and 1001 for tenth floor, room numbers in floors 1 to 9 should be configured as 0101, 0201, etc.
