Java.lang.StrictMath.round() Method


The java.lang.StrictMath.round(float a) method 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.It include these 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.


Following is the declaration for java.lang.StrictMath.round() method

public static int round(float a)


a − This is the floating-point value to be rounded to an integer.

Return Value

This method returns the value of the argument rounded to the nearest int value.




The following example shows the usage of java.lang.StrictMath.round() method.

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

   public static void main(String[] args) {

      float f1 = 98.22f , f2 = 23.44f;
      // returns the closest int to the argument 
      int roundValue = StrictMath.round(f1); 
      System.out.println("closest int value to " + f1 + " = " + roundValue);

      roundValue = StrictMath.round(f2); 
      System.out.println("closest int value to " + f2 + " = " + roundValue);

Let us compile and run the above program, this will produce the following result −

closest int value to 98.22 = 98
closest int value to 23.44 = 23
