DESCRIPTION

26       ::math::roman is a pure-Tcl library for converting between integers and
27       roman numerals. It also provides utility functions for sorting and per‐
28       forming arithmetic on roman numerals.
29
30       This   code   was   originally  harvested  from  the  Tcler's  wiki  at
31       http://wiki.tcl.tk/1823 and as such is free for any use  for  any  pur‐
32       pose.  Many  thanks to the ingeneous folk who devised these clever rou‐
33       tines and generously contributed them to the Tcl community.
34
35       While written and tested under Tcl 8.3, I expect this library will work
36       under all 8.x versions of Tcl.

COMMANDS

39       ::math::roman::toroman i
40              Convert  an  integer  to roman numerals. The result is always in
41              upper case. The value zero is converted to an empty string.
42
43       ::math::roman::tointeger r
44              Convert a roman numeral into an integer.
45
46       ::math::roman::sort list
47              Sort a list of roman numerals from smallest to largest.
48
49       ::math::roman::expr args
50              Evaluate an expression where the operands are all  roman  numer‐
51              als.
52
53       Of  these  commands  both toroman and tointeger are exported for easier
54       use. The other two are not, as they could interfer or be confused  with
55       existing Tcl commands.
