Special Conventions of HPPACLONGDIVD 

HPPACLONGDIVD includes the following conventions for compatibility with
the MPE V E procedure, LONGDIVD.

 *  Operand lengths are not validated.  Results are undefined if operand1 
    is longer than 28 digits, or if operand2 is longer than 36 digits.

 *  When operand2 is longer than 28 digits, only the first 28 digits (and
    the sign) are passed by the caller.  The remaining digits are assumed
    to be zeros, and no space needs to be allocated for them by the
    caller.  In effect, HPPACLONGDIVD will supply the necessary zeros by
    multiplying its local copy of operand2 by the appropriate power of
    ten.

 *  When using HPPACLONGDIVD, the caller is responsible for ensuring that
    the quotient does not exceed 28 digits.  If it does, results are
    undefined.

Possible Traps
