Common Lisp provides a large variety of operations related to numbers. This section provides an overview of those operations by grouping them into categories that emphasize some of the relationships among them.
The next figure shows operators relating to arithmetic operations.
* 1+ gcd + 1- incf - conjugate lcm / decf
