math::roman - Tools for creating and manipulating roman numerals SYNOPSIS
package require Tcl 8.3 package require math::roman ?1.0? ::math::roman::toroman i ::math::roman::tointeger r ::math::roman::sort list ::math::roman::expr args _________________________________________________________________ DESCRIPTION
::math::roman is a pure-Tcl library for converting between integers and roman numerals. It also provides utility functions for sorting and performing arithmetic on roman numerals. This code was originally harvested from the Tcler's wiki at http://wiki.tcl.tk/1823 and as such is free for any use for any purpose. Many thanks to the ingeneous folk who devised these clever routines and generously contributed them to the Tcl community. While written and tested under Tcl 8.3, I expect this library will work under all 8.x versions of Tcl. COMMANDS
::math::roman::toroman i Convert an integer to roman numerals. The result is always in upper case. The value zero is converted to an empty string. ::math::roman::tointeger r Convert a roman numeral into an integer. ::math::roman::sort list Sort a list of roman numerals from smallest to largest. ::math::roman::expr args Evaluate an expression where the operands are all roman numerals. Of these commands both toroman and tointeger are exported for easier use. The other two are not, as they could interfer or be confused with existing Tcl commands. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category math :: roman of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. KEYWORDS

math - Tcl Math Library SYNOPSIS
package require Tcl 8.2 package require math ?1.2.4? ::math::cov value value ?value ...? ::math::integrate list of xy value pairs ::math::fibonacci n ::math::max value ?value ...? ::math::mean value ?value ...? ::math::min value ?value ...? ::math::product value ?value ...? ::math::random ?value1? ?value2? ::math::sigma value value ?value ...? ::math::stats value value ?value ...? ::math::sum value ?value ...? _________________________________________________________________ DESCRIPTION
The math package provides utility math functions. Besides a set of basic commands, available via the package math, there are more specialised packages: o math::bigfloat - Arbitrary-precision floating-point arithmetic o math::bignum - Arbitrary-precision integer arithmetic o math::calculus::romberg - Robust integration methods for functions of one variable, using Romberg integration o math::calculus - Integration of functions, solving ordinary differential equations o math::combinatorics - Procedures for various combinatorial functions (for instance the Gamma function and "k out of n") o math::complexnumbers - Complex number arithmetic o math::constants - A set of well-known mathematical constants, such as Pi, E, and the golden ratio o math::fourier - Discrete Fourier transforms o math::fuzzy - Fuzzy comparisons of floating-point numbers o math::geometry - 2D geometrical computations o math::interpolate - Various interpolation methods o math::linearalgebra - Linear algebra package o math::optimize - Optimization methods o math::polynomials - Polynomial arithmetic (includes families of classical polynomials) o math::rationalfunctions - Arithmetic of rational functions o math::roman - Manipulation (including arithmetic) of Roman numerals o math::special - Approximations of special functions from mathematical physics o 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.
