Divider: 16
-FB243-
Use function block FB243 to divide one fixed-point binary number (16 bits) by another. The result
(quotient and remainder) is represented by two fixed-point binary numbers (16 bits each). The
divisor and the result are also scanned for zero. An eight-bit number must be transferred to a
16-bit word prior to division.
