round() returns ?

[Paul Salerno]

round (double) < -- returns long
I was under the impression that methods of Math return either int or double.
Where am I wrong?
TIA

If you look at the api, it states that the round method of the math class returns a long for a double and an int for a float hope this helps.

The point of the round() function is to convert a floating point value and return the closest integer value, so it doesn't makes sense to return a type double?

Hello Paul
how come u have such umpression ? You should check the apis' again... :-)
Rajinder is perfectly right on your answer.

I am not defending Paul because he sounds like a latin person , but he is right if he says that most of the methods in the Math class returns a double, apart from overloaded versions. round is the only method that doesn't do that.
Also most of the methods in the class Math take a double, apart from overloded ones. There is again one exception random that doesn't takes anything.
These knowledge was useful to me when taking the exam and it's easy to remember.
