Number Splitting
Instructions
Oh no, my numbers have stuck together! Luckily, we can split them apart with code.
Your code should be a function that takes an integer input from stdin or as an argument. You must split the number into single digits, keeping the order and possible duplicates of these digits. The output should be an array and it may be returned from the function or from stdout. Other forms of output may be discussed. The array elements may be a string or number.
Examples
345 -> [3, 4, 5]
12218 -> [1, 2, 2, 1, 8]
Scoring
This is code golf, so shortest code wins.
