for any number y , y * is defined as the greatest positive even integer less than or equal to y . what is the value of 5.0 – 5.0 * ?
"since y * is defined as the greatest positive even integer less than or equal to y , then 5.0 * = 4 ( the greatest positive even integer less than or equal to 5.0 is 4 ) . hence , 5.0 – 5.0 * = 5.0 - 4 = 1.0 answer : e ."
subtract(5.0, subtract(floor(5.0), const_1))
