how to remove unwanted coordinate numbers(metafun)

how to remove unwanted coordinate numbers(metafun)

[Jeong Dalyoung]

Dear all.

I try to draw a circle with points on it as following:

path p; p:= fullcircle scaled 5cm;
draw p;
pickup pencircle scaled 2mm;
k:=1;
for i = 2.2,3,3.5,4.5,5,7,0,.7,1.3:
	drawpoint point i of p;
	label.lft(decimal k, point i of p);
	k:= k+1;
endfor;

It draws a circle, points, label, but unwanted coordinate numbers like (60.43535, 36.97691), too.
I didn't see such numbers in any example in metafun document.

If I use z[k] like

z[k] = point i of P;
draw z[k]

Then  such a long numbers disappeared.

Is it the only way to surpress those numbers not using z?

Thank you for reading.

best regards,

Dalyoung

use drawdot then ... drawpoints is one of the tracing macros
