Java program to round a number
The java.lang.Math.round(float a) returns the closest int to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type int. Special cases −
If the argument is NaN, the result is 0.
If the argument is negative infinity or any value less than or equal to the value of Integer.MIN_VALUE, the result is equal to the value of Integer.MIN_VALUE.
If the argument is positive infinity or any value greater than or equal to the value of Integer.MAX_VALUE, the result is equal to the value of Integer.MAX_VALUE.
Example
import java.util.Scanner;
public class RoundingDecimalPlaces {
public static void main(String[] args) {
System.out.println("Enter a string value ::");
Scanner sc = new Scanner(System.in);
float f = sc.nextFloat();
System.out.println("Result of the given float after rounding:: " + Math.round(f));
}
}Output
Enter a string value :: 44584.2257 Result of the given float after rounding:: 44584
