For me, those lines only work for the next call to format.  After that,
again "unknown" numbers appear.

Best regards,

input metafun
prologues := 3;
beginfig(1);
  noftexpictures:=0;
  picture texpictures[];
  texpictures1 := btex$-$etex;
  label(format("%3f", -1234), (50,100));
  label(format("%3f", -1234), (50,50));
endfig;
end
