Whenever we think of numbers, we are actually thinking of them in relation to some base. Typically that base is 10. Each number can be decomposed as a combination of the powers of it's base.

134 = 1 * 10^2 + 3 * 10^1 + 4 * 10^0

function that takes a number and returns a list of it's decimal representation.

:"""Return a list representing the decimal representation of a number.>>> decimal(55055)[5, 5, 0, 5, 5]>>> decimal(-136)['-', 1, 3, 6]"""

Use OK to test your code:

We can also represent numbers in different bases. Think of how you could represent the number 5 in base 2. Essentially, how can you break the number 5 into powers of 2. It contains one 4 and one 1. In base 2, your digit overflows after 1, so this representation of numbers only has 1 and 0.

5 = 1 * 2^2 + 0 * 2^1 + 1 * 2^0

function that takes a number and returns a list of it's representation in base 2.

:"""Return a list representing the representation of a number in base 2.>>> binary(55055)[1, 1, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 1]>>> binary(-136)['-', 1, 0, 0, 0, 1, 0, 0, 0]"""
