Abstract
METODO Y ORDEN PARA REALIZAR UNA DIVISION APROXIMADA DE UN NUMERO CONSTANTE MEDIANTE UN NUMERO VARIABLE EN FORMA BINARIA. SE SUPONE QUE EL NUMERO VARIABLE SE COMPONE DE UN BIT DE CARACTER Y UNA VARIEDAD DE BITS QUE ESTABLECE EL VALOR ABSOLUTO DEL NUMERO. EL NUMERO SE CONVIERTE MEDIANTE LA FORMACION PRIMERO DE UNA PALABRA DIGITAL, SUSTITUYENDO CON CEROS LOGICOS CUALQUIERA DE LOS LOGICOS QUE TENGAN UN SIGNIFICADO MENOR QUE EL LOGICO MAS SIGNIFICATIVO DE LOS BITS. LUEGO SE FORMA UN NUMERO NUEVO EN FORMA BINARIA, LEYENDO EL BIT DE CARACTER DEL NUMERO VARIABLE COMO UN BIT DE CARACTER Y LEYENDO LOS BITS DE LA PALABRA DIGITAL EN UN ORDEN INVERSO. LA DISTRIBUCION PUEDE COMPRENDER PRINCIPALMENTE UNA RED DE PUERTA UNICA.
