for any number y , y * is defined as the greatest positive even integer less than or equal to y . what is the value of 8.2 – 8.2 * ?
"since y * is defined as the greatest positive even integer less than or equal to y , then 8.2 * = 4 ( the greatest positive even integer less than or equal to 5.2 is 4 ) . hence , 8.2 – 8.2 * = 8.2 - 6 = 2.2 answer : d ."
subtract(8.2, subtract(floor(8.2), const_1))
