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.
