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.
