Who knows about Math.abs()? give me the outputs :

Question

Math.abs('-1');
Math.abs(-2);
Math.abs(null);
Math.abs('');
Math.abs([]);
Math.abs([2]);
Math.abs([1,2]);
Math.abs({});
Math.abs('string');

Answer 1

In Java:-

Math.abs() function returns the absolute value of the number passed as argument i.e. either you enter a positive number or a negative number, it will always return a positive number...

e.g.
Math.abs(4) -> 4
Math.abs(-4) -> 4

Math.abs() takes only int,long,float and double as argument
