# Math floorDiv() method in Java

• Difficulty Level : Basic
• Last Updated : 20 Jun, 2018

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:

```Runtime Error :
Exception in thread "main" java.lang.ArithmeticException: / by zero
at java.lang.Math.floorDiv(Math.java:1052)
at Gfg2.main(File.java:13)
```
