Question

Give the output of the following: [2]

(a) Math.ceil(3.4) + Math.pow(2, 3);

(i) double b= −15.6; double a=Math.rint(Math.abs(b)); System.out.println(“a=” +a);​

Answer 1

Answer:

Explanation:

Math.floor method returns the largest double value that is less than or equal to the argument and is equal to a mathematical integer. As -5.0 is the largest mathematical integer less than -4.7 so it is the output. Note that -4.7 is a negative number so the largest integer less than -4.7 is -5.0 and not -4.0.
