A method includes receiving an unrounded mantissa value and a round bit associated with the unrounded mantissa value. The method also includes receiving a 2's complement signal that indicates whether the unrounded mantissa value results from a 1's complement operation. The method includes incrementing the unrounded mantissa value to provide an incremented value. The unrounded mantissa value is a non-incremented value. The method further includes providing one of the incremented value or non-incremented value as a rounded mantissa value responsive to the 2's complement signal.

An integrated circuit includes a first active region, a second active region, a first insulating region, a first contact and a second contact. The first and second active region extend in a first direction, are in a substrate, and are located on a first level. The second active region is separated from the first active region in a second direction. The first insulating region is over the first active region. The first contact extends in the second direction, overlaps the second active region, and is located on a second level different from the first level. The second contact extends in the first direction and the second direction, overlaps the first insulating region and the first contact. The second contact is electrically insulated from the first active region, and is located on a third level different from the first level and the second level.

A control circuit including a quadrature encoder circuit, a counter circuit, and a cutoff circuit is provided. The quadrature encoder circuit generates a first edge signal and a first direction signal according to a first external signal and a second external signal. The counter circuit performs a counting operation according to the first edge signal and the first direction signal. In response to the timer signal being enabled, the cutoff circuit prevents the first edge signal and the first direction signal from entering the counter circuit and provides a second edge signal and a second direction signal to the counter circuit so that the counter circuit performs the counting operation according to the second edge signal and the second direction signal.
