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 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.
