Deduction, perhaps mistaken: after the first iteration thru= this
loop:

   for (; integer &&p >=3D startp; ++expcnt)
   {
  tmp =3D modfl(integer * 0.1L , &integer);
  *p-- =3D tochar((int)((tmp + .01L) * 10));
   }

the value of `integer' had a .375 as its fraction.


A mistake is in multiplying by 0.1 instead of dividing by 10 and taking the=20= remainder. --part1_46.3c4de930.2c6a2e90_boundary--
