NAME
       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 pro-vides provides
       vides 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.
