    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  func-
                  tions of one variable, using Romberg integration
    
           ?      math::calculus - Integration of functions, solving ordinary dif-
                  ferential equations
    
           ?      math::combinatorics - Procedures for various combinatorial func-
                  tions (for instance the Gamma function and "k out of n")
    
           ?      math::complexnumbers - Complex number arithmetic
    
    
           ?      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  mathe-
                  matical 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  varia-
