Definition:Lattice Point/Rational

Definition

Let $\CC$ be a cartesian coordinate system of $n$ dimensions.

Let $P = \tuple {a_1, a_2, \ldots, a_n}$ be a point in $\CC$.

$P$ is a rational lattice point of $\CC$ if and only if $a_1, a_2, \ldots, a_n$ are all rational numbers.

Also known as

A rational lattice point can also be referred to as a rational point.
