The latest baseline of trio (v 1.7) now handles these numbers appropriately.
Consider the following statement

  printf("%30.24f\n%30.24f\n%30.24f\n", 39413.80, 1.4, (2.0/3.0));

The libc printf on my machine outputs

  39413.800000000002910383045673
      1.399999999999999911182158
      0.666666666666666629659233

whereas trio outputs

  39413.800000000000000000000000
      1.400000000000000000000000
      0.666666666666667000000000

Let me know if you want to use this, and I'll upgrade libxml to the latest
trio baseline.
