  25 /*  FUNCTION
  26         Convert a floating-point number from an ASCII decimal
  27         representation into a double-precision format.
  28
  29     INPUTS
  30         str - The string which should be converted. Leading
  31                 whitespace are ignored.
  32         endptr - If this is non-NULL, then the address of the first
  33                 character after the number in the string is stored
  34                 here.
  35
  36     RESULT
  37         The float value of the string. The first character after the number
  38         is returned in *endptr, if endptr is non-NULL. If no digits can
  39         be converted, *endptr contains str (if non-NULL) and 0 is
  40         returned.
