Subject: Metapost label - Truncating digits after decimal point
Date: Sat, 28 Nov 2009 09:56:32 -0500 [thread overview]
Message-ID: <3b4b12310911280656x6c4b5023g112ba92b278d5df4@mail.gmail.com> (raw)
Hi,
Is it possible to truncate the digits after decimal point in Metapost
when using textext()? Please see the minimal example below which
produces 1.84375. Can I just keep the first digit and have it produce
1.8 ?
Thanks.
\setuppapersize[letter][letter]
\setupcolors[state=start]
\starttext
\startuseMPgraphic{Figure}
u := 1cm;
pickup pencircle scaled 2pt; % default pen thickness
%TheFunction
vardef f(expr x) =
(10/x)-x*((0.5)**x)
enddef;
%Labels
label.lft(textext(decimal f(5)),(0,f(5)) scaled u);
\stopuseMPgraphic
\useMPgraphic{Figure}
\stoptext
