for any number z , z * is defined as the greatest positive even integer less than or equal to y . what is the value of 6.30 – 6.30 * ?
"since z * is defined as the greatest positive even integer less than or equal to z , then 6.30 * = 6 ( the greatest positive even integer less than or equal to 6.30 is 6 ) . hence , 6.30 – 6.30 * = 6.30 - 6 = 0.30 answer : e ."
subtract(6.30, floor(6.30))
