Problem Statement
You need to round the floating-point numbers to integers in Java.
Solution
When you cast a floating value to integer in Java , the value gets truncated. For example , the value 7.8989 when casted to integer will become 7.
In order to round he floating-point numbers correctly , you can use the Math.round() method.
The Math.round method has a 2 overloaded forms.
The first one takes the double as input and returns long. The second one takes the float value and returns integer.
public class Main { public static void main(String[] args) { System.out.println("Abundantcode.com Java Tutorials"); double input1 = 76.88967; long output1 = Math.round(input1); System.out.println("Long value is " + output1); int output2 = Math.round(output1); System.out.println("int value is " + output2); } }
The output of the above program is
