num_to_alphanumeric
The function num_to_alphanumeric converts integers to alphanumeric codes.
For example: 1=A, 2=B, 26=Z, 27=AA, 28=AB, 52=AZ, 53=BA etc.
Here’s how the function works:
- We start with the input number.
- In each iteration, we calculate the remainder after dividing by 26 (the number of letters in the alphabet).
- We convert the remainder to the corresponding letter (‘A’ for 1, ‘B’ for 2, and so on).
- We prepend the letter to the result string.
- We update the input number by subtracting the remainder and dividing by 26.
- Repeat until the input number becomes zero.
Now you can use this function to convert numbers to the desired alphanumeric code. For example:
NUM_TO_ALPHANUMERIC(1) returns 'A'.
NUM_TO_ALPHANUMERIC(27) returns 'AA'.
NUM_TO_ALPHANUMERIC(52) returns 'AZ'.
NUM_TO_ALPHANUMERIC(53) returns 'BA'.
