for any number y , y * is defined as the greatest positive even integer less than or equal to y . what is the value of 9.2 – 9.2 * ?
"since y * is defined as the greatest positive even integer less than or equal to y , then 9.2 * = 8 ( the greatest positive even integer less than or equal to 9.2 is 4 ) . hence , 9.2 – 9.2 * = 9.2 - 8 = 1.2 answer : b ."
subtract(9.2, subtract(floor(9.2), const_1))
