       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 Trackers [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 unified diffs, i.e the output of diff -u.
