Math Class - Very Urgent

[Mahesh Bansal]

what is the nearest integer to -11.2.
And what method of Math class we should use to get the nearest integer value of -11.2.
Thanks in advance.

I think it's the Math.round(float f) method.
float f=Math.round(-11.2)
This will give f the value of -11 as an integer value.
And Since -11 is the nearest integer to -11.2, you can say it's the "public int Math.round(float f)" method.
I hope I am correct, am I??

Sorry, in the above code statement, it should be:
int f=Math.round(float f)

AND NOT
float f=Math.round(float f)
Got my mistake!!

Math class has two round methods!
static�long round(double�a) ����������
Returns the closest long to the argument.
and
static�int round(float�a) ����������
Returns the closest int to the argument.
and in java if you do not specify anything
-11.2 will be a double and not a float
so the first one will be used

Again a silly mistake!!

Other important concepts needed for the exam are:
1) when to use Math.round() vs. Math.floor() or Math.ceil()
2) Math.floor() and Math.ceil() return double values.

Thanks a ton for the advise.
