Question

Given: double k = Math.rint(−9.4) + Math.sqrt(9.0); 

Options

• −5.0

• −6.0

• −6.4

• −5.4

Answer 1

−6.0

Explanation:

Math.rint(−9.4) will return −9.0, which is the nearest integer to −9.4. Math.sqrt(9.0) yields 3.0. Therefore, the expression is solved as follows: 

k = Math.rint(−9.4) + Math.sqrt(9.0);

k = −9.0 + 3.0

k = −6.0
