Question

Given: double a = - 8.35;

double p = Math.abs(Math.floor(a));

What will be the final value stored in the variable p? 

विकल्प

• 9.0

• 8.0

• 7.0

• 8.5

Answer 1

9.0

Explanation:

The Math.floor() method returns the greatest double number that is less than or equal to the argument and equals a mathematical integer. As -9.0 is the largest mathematical integer less than -8.35, it is returned in this circumstance. Math.abs() returns the absolute value of its argument, so the result is 9.0. The expression is resolved as follows:

p = Math.abs(Math.floor(a));

p = Math.abs(Math.floor(-8.35));

p = Math.abs(-9.0);

p = 9.0
