public class Constant
extends Object

A constant in an expression.
Some expressions needs constants. For instance it is impossible to perform trigonometric calculus without using pi. A constant allows you to use mnemonic in your expressions instead of the raw value of the constant.
A constant for pi would be defined by :
Constant<Double> pi = new Constant<Double>("pi");
With such a constant, you will be able to evaluate the expression "sin(pi/4)"
