Abstract
A method and an arrangement for performing an approximate division of a constant number by a variable number in binary form. The variable number is presumed to consist of a character bit and a plurality of bits which state the absolute value of the number. The number is converted by first forming a digital word, by substituting with logic zeroes any logic ones that have a lower significance than the most significant logic one of the bits. There is then formed a new number in binary form, by reading the character bit of the variable number as a character bit and by reading the bits in the digital word in a reversed order. The arrangement may mainly comprise a single gate network.
