Can you please describe the user story for this?

Yolo comes from a society that does not have an implicit bias towards base 10, and instead uses a variety of number scales for cultural reasons. Yolo is marginalized by the base 10 population for not being able to translate thirteen into this new monobase system. Yolo becomes destitute due to his inability to utilize thirteen and sells his children into slavery to survive. Yolo dies sad, alone, and confused.

Should be ready for merge.

User story:
is(D).thirteen();
OR
is(12).thirteen();
Reason: If we support octal and binary, we should support all base systems!! Otherwise this is just the man trying to tell us which base system to use.
