Details:

When running the test suite with Octave hg id 9d9e01986105 built on Ubuntu
19.10, I see the following two tests marked as regressions:

 [old_fmt, old_spacing] = format ();

   assert (rats (2.0005, 9), "4001/2000");
   assert (rats (-2.0005, 10), "-4001/2000");
   assert (strtrim (rats (2.0005, 30)), "4001/2000");
   assert (pi - str2num (rats (pi, 30)), 0, 4 * eps);
   assert (e - str2num (rats (e, 30)), 0, 4 * eps);
   assert (rats (123, 2), " *");
   v = 1 / double (intmax);
   err = v - str2num (rats (v, 12));
   assert (err, 0, 4 * eps);
