  Log:
  Revert rev 1.8, which causes small (e.g. 2 ulp) errors for some
  inputs.  The trouble with replacing two floats with a double is that
  the latter has 6 extra bits of precision, which actually hurts
  accuracy in many cases.  All of the constants are optimal when float
  arithmetic is used, and would need to be recomputed to do this right.
