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.

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.
37
39 ::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 ::roman::tointeger r
44 Convert a roman numeral into an integer.
45
46 ::roman::sort list
47 Sort a list of roman nnumerals from smallest to largest.
48
49 ::roman::expr args
50 Evaluate an expression where the operands are all roman numer‐
51 als.
