All Implemented Interfaces:

Cloneable, Expression

public class Round

extends Operation

This is a concrete implementation for the round operation. Round is defined as nearest integer, with rounding done to an even number if the operand is exactly between two integers. This is a unary operator, *???but can also work on lists???*.
