12.1.1 Numeric Operations

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.

Operators relating to Arithmetic.
* 1+ gcd
+ 1- incf
- conjugate lcm
/ decf

The next figure shows defined names relating to exponential, logarithmic, and trigonometric operations.

Defined names relating to Exponentials, Logarithms, and Trigonometry.
abs cos signum
acos cosh sin
acosh exp sinh
asin expt sqrt
asinh isqrt tan
