::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.
