Hi,
I may have found the bug that broke my metafun
file. Looks like it is connected to odd function.
This snippet of code:
\starttext
\startMPpage
path p;p:=origin--(20,20);
draw p;
draw p reflectedabout ((10,10),(10,-10)) withcolor red;
for i=1 upto 2:
if odd i:
draw p yshifted 20 withcolor green;
else:
draw p xshifted 20 withcolor blue;
fi;
endfor;
\stopMPpage
\stoptext
does not compile as I would expect (no green
line drawn). I noticed such behaviour in
2020.12.30 16:45
version. I updated a few minutes ago and have
the same output.
I hope I didn't miss anything.
Best regards,
Damien Thiriet

for now use this:
let odd = relax;
vardef odd expr n = ((abs(n) mod 2) == 1) enddef ;
I got it fixed (scaled, double and decimal) but no upload now
