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

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

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

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

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

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

       ::math::productvalue ?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::sigmavaluevalue ?value...?
              Return the sample standard deviation of two or more numeric values.

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

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

       This document, and the package it describes, will undoubtedly contain bugs and  other  problems.   Please
       report  such  in the category math of the TcllibTrackers [http://core.tcl.tk/tcllib/reportlist].  Please
       also report any ideas for enhancements you may have for either package and/or documentation.

       When proposing code changes, please provide unifieddiffs, i.e the output of diff-u.

       Note further that attachments are strongly preferred over inlined patches. Attachments  can  be  made  by
       going  to the Edit form of the ticket immediately after its creation, and then using the left-most button

       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
