Math floorDiv() method in Java

The java.lang.Math.floorDiv() is a built-in math function in java which returns the largest (closest to positive infinity) int value that is less than or equal to the algebraic quotient. As floorDiv() is static, so object creation is not required.

Syntax:

public static int floorDiv(data_type x, data_type y)

Parameter: The function accepts two parameters as described below.

• x: The first parameter refers to the dividend value.
• y: The second parameter refers to the divisor value.

The parameters can be data-type int or long.

Exception:

• ArithmeticException: It throws ArithmeticException if the divisor is zero.

Return Value: This method returns the largest (closest to positive infinity) integer value that is less than or equal to the algebraic quotient.

Below programs illustrate the java.lang.Math.floorDiv() method:

Program 1:

// Java program to demonstrate working
// of java.lang.Math.floorDiv() method
import java.lang.Math;

class Gfg1{

    // driver code
    public static void main(String args[])
    {
        int a = 25, b = 5;
        System.out.println(Math.floorDiv(a, b));

        // 125/50 value is 2.5, but as output is integer
        // less than or equal to 2.5, So output is 2
        int c = 125, d = 50;
        System.out.println(Math.floorDiv(c, d));
    }
}

Output:

5
2

Program 2:

// Java program to demonstrate working
// of java.lang.Math.floorDiv() method
import java.lang.Math;

class Gfg2 {

    // driver code
    public static void main(String args[])
    {
        int x = 200;
        int y = 0;

        System.out.println(Math.floorDiv(x, y));
    }
}

Output:
