NAME

     ldiv, lrem - long division



SYNOPSIS

     ldiv(hidividend, lodividend, divisor)



     lrem(hidividend, lodividend, divisor)



DESCRIPTION

     The concatenation of the signed 16-bit  hidividend  and  the

     unsigned  16-bit  lodividend is divided by divisor.  The 16-

     bit signed quotient is  returned  by  ldiv  and  the  16-bit

     signed  remainder  is  returned  by  lrem.  Divide check and

     erroneous results will occur unless  the  magnitude  of  the

     divisor is greater than that of the high-order dividend.



     An integer division of an  unsigned  dividend  by  a  signed

     divisor may be accomplished by



             quo = ldiv(0, dividend, divisor);



     and similarly for the remainder operation.



     Often both  the  quotient  and  the  remainder  are  wanted.

     Therefore  ldiv  leaves  a  remainder  in  the external cell

     ldivr.



BUGS

     No divide check check.
