    {
        double i;
        System.out.println("_________________________________________________________");
        System.out.println("| Number" + "\t" + "| abs " + "\t" + "| rint" + "\t" + "| round" + "\t" +"| sqrt ");
        System.out.println("_________________________________________________________");
        for(i = -2.0 ; i< 5 ; )
        {
            System.out.println("|  "+i+"  " + "\t" + "| " + Math.abs(i)  + " " + "\t" + "| " + Math.rint(i) + " " + "\t" + "| " + Math.round(i)+ " " + "\t" + "| " +  Math.sqrt(i));
            i = i+0.5; 
        }
    }

This is for those struggling for Math.rint(), hope this helps..



How Math.rint() works:

EVEN NUMBER CASES:
(1) Math.rint(4.4) = 4.0		
[This is basically just like math.round it will round to lowest]

(2) Math.rint(4.5) = 4.0		
[Since, the number main decimal number (4) is an even number, instead of rounding of to higher number like 5.0 from decimal point 0.5 it will round of to 4.0, unlike .round function] [For such no. if u want to round it to 5.0, the decimal shud be 0.6 or greater, like the case below] 

ODD NUMBER CASES:
(3) Math.rint(4.6/4.7 or greater) = 5.0


Now for the bottom 3 examples, the main decimal number (3) is an odd no, so it will obey standard rules of rounding, i.e. rounding will start from the 0.5 itself]  Exactly like Math.round() function.. except round returns int type..

(4) Math.rint(3.4) = 3.0 

(5) Math.rint(3.5) = 4.0

(6) Math.rint(3.6/3.7 or greater) = 4.0




*Negative numbers are the same.. just ignore the minus sign and follow above procedure, then put the minus sign back in the answer
