[NTG-context] Metapost label - Truncating digits after decimal point

28 Nov 2009

      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
