How to round a number (float or double to integer) using the round method?

We can use the round static method of the Java Math class to round a float or double number.


This method returns the closest integer number to the argument.


Note: The round(float f)  method returns an int value while the round(double d)  method returns a long value.

Internally, 0.5 is added to the argument number and a floor value is taken. The result is then cast to an integer value as given below.
