+The code to generate the table in strtofr.c was written in 2004 and not
+updated since. Not sure if this case was ever actually handled.
+Without this check, we end up dividing by zero, which creates problematic
+results.
+To fix this, check if the divisor is zero, and if it is, early exit (and
+fill the rest of the continued fraction with zeros).
