Definition:Hexatrigesimal Notation

Definition
Hexatrigesimal notation is the technique of expressing numbers in base $36$.

Every number $x \in \R$ is expressed in the form:
 * $\ds x = \sum_{j \mathop \in \Z} r_j 36^j$

where:
 * $\forall j \in \Z: r_j \in \set {0, 1, \ldots, 35}$

In order to be able to represent numbers in such a format conveniently and readably, it is necessary to render the digits $10$ to $35$ using single characters.

The convention is using $\mathrm A$ to $\mathrm Z$ to represent digit values $10$ to $35$.
