.TH "math::roman"  1\&.1 tcllib "Tcl Math Library"
.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
math::roman \- Tools for creating and manipulating roman numerals
.SH SYNOPSIS

\fB::math::roman::toroman\fR \fIi\fR

.SH DESCRIPTION
.PP
\fB::math::roman\fR 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\&.
.PP
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\&.
.PP
While written and tested under Tcl 8\&.3, I expect this library
will work under all 8\&.x versions of Tcl\&.
.SH COMMANDS
.TP
\fB::math::roman::toroman\fR \fIi\fR
Convert an integer to roman numerals\&. The result is always in
upper case\&. The value zero is converted to an empty string\&.
.TP
\fB::math::roman::tointeger\fR \fIr\fR
Convert a roman numeral into an integer\&.
.TP
\fB::math::roman::sort\fR \fIlist\fR
Sort a list of roman numerals from smallest to largest\&.
.TP
\fB::math::roman::expr\fR \fIargs\fR
Evaluate an expression where the operands are all roman numerals\&.
.PP
Of these commands both \fItoroman\fR and \fItointeger\fR are exported
for easier use\&. The other two are not, as they could interfer or be
confused with existing Tcl commands\&.
.SH "BUGS, IDEAS, FEEDBACK"
This document, and the package it describes, will undoubtedly contain
bugs and other problems\&.
Please report such in the category \fImath :: roman\fR of the
\fITcllib Trackers\fR [http://core\&.tcl\&.tk/tcllib/reportlist]\&.
Please also report any ideas for enhancements you may have for either
package and/or documentation\&.
.PP
When proposing code changes, please provide \fIunified diffs\fR,
i\&.e the output of \fBdiff -u\fR\&.
.PP
Note further that \fIattachments\fR are strongly preferred over
inlined patches\&. Attachments can be made by going to the \fBEdit\fR
form of the ticket immediately after its creation, and then using the
left-most button in the secondary navigation bar\&.
