### Function: round

Return the nearest integer to ARG.

With optional DIVISOR, return the nearest integer to ARG/DIVISOR.

Rounding a value equidistant between two integers may choose the

integer closer to zero, or it may prefer an even integer, depending on

your machine. For example, (round 2.5) can return 3 on some

systems, but 2 on others.
