ABSTRACT:
Computing an output interval includes producing a first product resulting from a conditional multiplication using a first operand, a second operand, and a third operand. Next a second product is produced resulting from the conditional multiplication using the first operand, the second operand, and the third operand. Then a third product is produced resulting from the conditional multiplication using the first operand, the second operand, and the third operand. Next a fourth product is produced resulting from the conditional multiplication using the first operand, the second operand, and the third operand. And finally, the output interval is produced including an output interval lower-point and an output interval upper-point, the output interval lower-point being the minimum of the first product and the third product, and the output interval upper-point being the maximum of the second product and the fourth product.
