DESCRIPTION

       The math package provides utility math functions.

       Besides  a  set  of  basic  commands,  available  via  the  package  math,  there are more
       specialised packages:

       •      math::bigfloat - Arbitrary-precision floating-point arithmetic

       •      math::bignum - Arbitrary-precision integer arithmetic

       •      math::calculus::romberg - Robust integration methods for functions of one variable,
              using Romberg integration

       •      math::calculus - Integration of functions, solving ordinary differential equations

       •      math::combinatorics  - Procedures for various combinatorial functions (for instance
              the Gamma function and "k out of n")

       •      math::complexnumbers - Complex number arithmetic

       •      math::constants - A set of well-known mathematical constants, such as  Pi,  E,  and
              the golden ratio

       •      math::fourier - Discrete Fourier transforms

       •      math::fuzzy - Fuzzy comparisons of floating-point numbers

       •      math::geometry - 2D geometrical computations

       •      math::interpolate - Various interpolation methods

       •      math::linearalgebra - Linear algebra package

       •      math::optimize - Optimization methods

       •      math::polynomials   -   Polynomial   arithmetic  (includes  families  of  classical
              polynomials)

       •      math::rationalfunctions - Arithmetic of rational functions

       •      math::roman - Manipulation (including arithmetic) of Roman numerals

       •      math::special - Approximations of special functions from mathematical physics

       •      math::statistics - Statistical operations and tests

BASIC COMMANDS

       ::math::cov value value ?value ...?
              Return the coefficient of variation expressed as percent of  two  or  more  numeric
              values.

       ::math::integrate list of xy value pairs
              Return  the  area under a "curve" defined by a set of x,y pairs and the error bound
              as a list.

       ::math::fibonacci n
              Return the n'th Fibonacci number.

       ::math::max value ?value ...?
              Return the maximum of one or more numeric values.

       ::math::mean value ?value ...?
              Return the mean, or "average" of one or more numeric values.

       ::math::min value ?value ...?
              Return the minimum of one or more numeric values.

       ::math::product value ?value ...?
              Return the product of one or more numeric values.

       ::math::random ?value1? ?value2?
              Return a random number.  If no arguments are given, the number is a floating  point
              value  between  0  and 1.  If one argument is given, the number is an integer value
              between 0 and value1.  If two arguments are given, the number is an  integer  value
              between value1 and value2.

       ::math::sigma value value ?value ...?
              Return the population standard deviation of two or more numeric values.

       ::math::stats value value ?value ...?
              Return the mean, standard deviation, and coefficient of variation (as percent) as a
              list.

       ::math::sum value ?value ...?
              Return the sum of one or more numeric values.
