Hi,
Like this:
metapost.registerscript("scrutenized", function()
local p = mp.scan.path()
local r = math.round
local d = 10^mp.scan.numeric()
for i=1,#p do
local pi = p[i]
pi[1] = r(pi[1] * d) / d
pi[2] = r(pi[2] * d) / d
end
local x1 = r(p[1][1])
local y1 = r(p[1][2])
local n = 1
local t = { p[1], cycle = p.cycle }
for i=2,#p do
local pi = p[i]
local x2 = r(pi[1])
local y2 = r(pi[2])
if x1 ~= x2 or y1 ~= y2 then
n = n + 1
t[n] = p[i]
x1 = x2
y1 = y2
end
end
mp.inject.path(t)
end)
\stopluacode
\startMPdefinitions{doublefun}
newscriptindex mfid_scrutenized ; mfid_scrutenized := scriptindex
"scrutenized" ;
primarydef p scrutenized n =
runscript mfid_scrutenized p n
enddef ;
\stopMPdefinitions
and then
p[1] := p[1] scrutenized 5 ; % 5 decimals
p[2] := p[2] scrutenized 5 ; % 5 decimals
