                      2: .sh NAME
                      3: ldiv \*- long division
                      4: .sh SYNOPSIS
                      5: .ft B
                      6: ldiv(hidividend, lodividend, divisor)
                      7: .s3
                      8: lrem(hidividend, lodividend, divisor)
                      9: .ft R
                     10: .sh DESCRIPTION
                     11: The
                     12: concatenation of the signed
                     13: 16-bit
                     14: .it hidividend
                     15: and the unsigned 16-bit
                     16: .it lodividend
                     17: is divided by
                     18: \fIdivisor\fR.
                     19: The 16-bit signed quotient is returned by
                     20: .it ldiv
                     21: and the 16-bit signed remainder is returned by
                     22: .it lrem.
                     23: Divide check and erroneous results
                     24: will occur
                     25: unless the magnitude of the
                     26: divisor is greater than that of the high-order
                     27: dividend.
                     28: .s3
                     29: An integer division of an unsigned
                     30: dividend by a signed divisor may
                     31: be accomplished by
                     32: .s3
                     33:        quo = ldiv(0, dividend, divisor);
                     34: .s3
                     35: and similarly for the remainder operation.
                     36: .s3
                     37: Often both the quotient and the remainder are wanted.
                     38: Therefore
                     39: .it ldiv
                     40: leaves a remainder in the external cell
                     41: .it ldivr.
                     42: .sh BUGS
                     43: No divide check check.
