All Implemented Interfaces:

Cloneable, Expression

public class Trunc

extends Operation

This is a concrete implementation for the trunc (truncation) operation. Trunc is also known as "integer part," the result is equivalent to "round to zero," since it rounds to the nearest integer closer to zero. This is a unary operator, *???but can also work on lists???*.
