According to Jim Meyering on 4/14/2008 11:13 AM:

| if (xstrtold (x_str + layout.prefix_len, NULL, &x_val, c_strtold)
| - && x_val == last)
| + && abs_rel_diff (x_val, last) < DBL_EPSILON)
Don't you need to scale the result of abs_rel_diff to be on the same order
of magnitude as x_val? DBL_EPSILON represents 1 ulp of 1.0, but 2 ulps of
0.5. It seems like what you are really trying to do here is terminate
when the result is within 1 or 2 ulps, not when the result is less than
DBL_EPSILON off.

Don't work too hard, make some time for fun as well!
