Operation
dst ← dst + src + C
The source operand, along with the setting of the Carry (C) Flag, is added
to the destination operand. Two’s complement addition is performed. The
sum is stored in the destination operand. The contents of the source oper-
and are not affected. In multiple precision arithmetic, this instruction per-
mits the carry from the addition of low order operands to be carried into
the addition of high order operands.
