Base change

Returns a number in a different base. The representation of a number $n$ in base $b$ is $[a_{0}, a_{1}, . . ., a_{k}]$ if

$n = a_{0} b^{0} + a_{1} b^{1} + a_{2} b^{2} + \dots + a_{k} b^{k}$

with $a_{i} < b$ .

base_change(Vector, Integer)

Given an integer $n$ in decimal base and a base $b$ , returns a vector in the desired base in the order specified above.

Given a vector $v$ and a base $b$ , where $v$ is the representation in base $b$ in the order specified above, returns the number in decimal base.
