::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.









  
::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.








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.
