Example
Following is an example of the usage of this method −
class Example { static void main(String[] args) { double d = 100.675; double e = 100.500; float f = 100; float g = 90f; System.out.println(Math.round(d)); System.out.println(Math.round(e)); System.out.println(Math.round(f)); System.out.println(Math.round(g)); } }
When we run the above program, we will get the following result −
