Rounding is the process of approximation of a value of a variable to a multiple of a given power of whatever number base one is working in (usually decimal).

Let $n \in \Z$ be an integer.

Let $x \in \R$ be a real number.

Let $y \in \R$ such that:

$y = 10^n \left\lfloor{\dfrac x {10^n} + \dfrac 1 2}\right\rfloor$

Then $y$ is defined as $x$ rounded to the nearest $n$th power of $10$.
