Answer 1

Question:

Find the output of the following Java  code line:

System.out.println(math.floor(-7.2))

(A) -7

(B) -8

(C) -7.4

(D) -7.0

Answer:

(B) -8  is the correct answer.

Explanation:

Floor function in Java is used to print the lower limit value of the number entered.

As in above example the lower limit of number is -8 and upper limit of number is -7

But, if the number would have been 7.2 then the lower limit would have been 7 and upper limit would have been 8.

On number line we can see this that as we go on towards the positive side of number which is after 0 value keeps on increasing and before 0 value gets decreasing.

That's why the above thing happens.
