z=Math.sqrt(549);

z=Math.min(5,3,6,789,867,344);

z=Math.ceil(4.4);//works in decimal no. ceiling higher round

z=Math.floor(5.3);//works in decimal :floor lower round

z=Math.pow(5,3);

z=Math.random();//generates random no. between 0 and 1

z=100*Math.random();//generates random no. between 1 and 100

z=50+(100-50)*Math.random();//generates no. between 50 and 100

 //formula: L+(H-L)*no.

z=Math.abs(-5); 

z=Math.ceil(50+(100-50)*Math.random());//generates randomm no. int: you can use floor also

console.log(z)
