Java Math floor(double a) method example

Method Returns :

The floor(double a) method simply returns returns the largest double value that is less than or equal to the argument and is equal to an integer. Special cases:

• If the argument value is already equal to a mathematical integer, then the result is the same as the argument.
• If the argument is NaN or an infinity or positive zero or negative zero, then the result is the same as the argument.

Compatibility Version :

Requires Java 1.0 and up

Exception :

N/A

Java Code Example :

This java example source code demonstrates the use of floor(double a) method of Math class. Basically we just get the floor value of a double variable coming from the user input.

package com.javatutorialhq.java.examples;

import static java.lang.System.*;

import java.util.Scanner;

/*
 * This example source code demonstrates the use of 
 * floor(double a) method of Math class
 * Get the floor value of the user input
 */

public class MathFloor {

	public static void main(String[] args) {
		// ask for user input
		out.print("Enter a value:");
		Scanner scan = new Scanner(System.in);
		// use scanner to get user console input
		double value = scan.nextDouble();		
		// get the ceiling of a value
		double floorValue = Math.floor(value);
		out.println("floor of "+value+" = "+floorValue);		
		// close the scanner object to avoid memory leak
		scan.close();

	}

}

Sample Output :

Running the abs(double a) method example source code of Math class will give you the following output

Enter a value:132.32
floor of 132.32 = 132.0
