DESCRIPTION

40       The math package provides utility math functions.
41
42       Besides  a set of basic commands, available via the package math, there
43       are more specialised packages:
44
45       ·      math::bigfloat - Arbitrary-precision floating-point arithmetic
46
47       ·      math::bignum - Arbitrary-precision integer arithmetic
48
49       ·      math::calculus::romberg - Robust integration methods  for  func‐
50              tions of one variable, using Romberg integration
51
52       ·      math::calculus - Integration of functions, solving ordinary dif‐
53              ferential equations
54
55       ·      math::combinatorics - Procedures for various combinatorial func‐
56              tions (for instance the Gamma function and "k out of n")
57
58       ·      math::complexnumbers - Complex number arithmetic
59
60       ·      math::constants  -  A  set of well-known mathematical constants,
61              such as Pi, E, and the golden ratio
62
63       ·      math::fourier - Discrete Fourier transforms
64
65       ·      math::fuzzy - Fuzzy comparisons of floating-point numbers
66
67       ·      math::geometry - 2D geometrical computations
68
69       ·      math::interpolate - Various interpolation methods
70
71       ·      math::linearalgebra - Linear algebra package
72
73       ·      math::optimize - Optimization methods
74
75       ·      math::polynomials - Polynomial arithmetic (includes families  of
76              classical polynomials)
77
78       ·      math::rationalfunctions - Arithmetic of rational functions
79
80       ·      math::roman  -  Manipulation  (including  arithmetic)  of  Roman
81              numerals
82
83       ·      math::special - Approximations of special functions from  mathe‐
84              matical physics
85
86       ·      math::statistics - Statistical operations and tests
87

BASIC COMMANDS

89       ::math::cov value value ?value ...?
90              Return  the coefficient of variation expressed as percent of two
91              or more numeric values.
92
93       ::math::integrate list of xy value pairs
94              Return the area under a "curve" defined by a set  of  x,y  pairs
95              and the error bound as a list.
96
97       ::math::fibonacci n
98              Return the n'th Fibonacci number.
99
100       ::math::max value ?value ...?
101              Return the maximum of one or more numeric values.
102
103       ::math::mean value ?value ...?
104              Return the mean, or "average" of one or more numeric values.
105
106       ::math::min value ?value ...?
107              Return the minimum of one or more numeric values.
108
109       ::math::product value ?value ...?
110              Return the product of one or more numeric values.
111
112       ::math::random ?value1? ?value2?
113              Return  a  random number.  If no arguments are given, the number
114              is a floating point value between 0 and 1.  If one  argument  is
115              given,  the number is an integer value between 0 and value1.  If
116              two arguments are given, the number is an integer value  between
117              value1 and value2.
118
119       ::math::sigma value value ?value ...?
120              Return  the population standard deviation of two or more numeric
121              values.
122
123       ::math::stats value value ?value ...?
124              Return the mean, standard deviation, and coefficient  of  varia‐
125              tion (as percent) as a list.
126
127       ::math::sum value ?value ...?
128              Return the sum of one or more numeric values.
