That is a bug in printf.icn's fixnum() procedure! Here's one
way to fix the problem - there's probably a better way:
In ipl/procs/printf.icn, in the procedure fixnum(x, prec),
change the last few lines from:
------------------------------------------------------
frac := left(frac, prec, "0")
return int || "." || frac
end
------------------------------------------------------
to:
------------------------------------------------------
frac := left(frac, prec, "0")
if x < 0 then int := "-"||int
return int || "." || frac
end
------------------------------------------------------
(The problem is that integer("-0.1234") is 0...)
