とする除算器。 In the divider, a digit detector that calculates the significant digits of the divisor , a comparator that compares the output of the map with a given threshold value, and an interrupt handler that causes a trap based on the significant signal of the comparator, interrupts the division, and sets the quotient to 0. Divider.
