Question

What will be the final values stored in variables when executed?

double a = -99.51;

double b = -56.25;

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

ii) double q = Math.sqrt(Math.abs(b));​

Answer 1

Question:-

• What will be the final value of a and b :-

double a= -99.51;

doubt b= -56.25;

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

II) double q = Math.sqrt(Math.abs(b));

Answer:-

I) 100.0

Explaination:-

• Math.abs(Math.floor(-99.51)
• Math.floor() rounds off the number to the next lower integer i.e. Here it will return -100.0. (Note: Math.floor() always returns double data type value.)
• Math.abs() will return the absolute value of the number i.e. Here it will return 100.0

II) 7.5

Explanation:-

• Math.sqrt(Math.abs(-56.25))
• Math.abs() will return absolute value of the number i.e. Here it will return 56.25
• Now, Math.sqrt() returns square root of the positive number (as square root of negative number is not possible) so here it will return the square root of 56.25 which is 7.5
