Java Math.floorDiv() method

The java.lang.Math.floorDiv() is used to find the largest integer value that is less than or equal to the algebraic quotient. This method first divide the first argument by the second argument and then performs a floor() operation over the result and returns the integer that is less or equal to the quotient.

Syntax

  public static int floorDiv(int x, int y)  public static long floorDiv(long x, int y)  public static long floorDiv(long x, long y)  

Parameter

Return

  This method returns the largest value that is less than or equal to the algebraic quotient.  

If the first argument is int or long value and second argument is -1, this method will return the first argument as output.
If the second argument is zero, this method will throw ArithmeticException.

Example 1

  public class FloorDivExample1  {      public static void main(String[] args)       {          int x = 25;          int y= 3;          // 25/3 value is 8.33 so floor(8.33) = 8           System.out.println(Math.floorDiv(x, y));      }  }  

Test it Now

Output:

Example 2

  public class FloorDivExample2  {      public static void main(String[] args)       {          int x = -25;          int y= 3;          // -25/3 value is -8.333 so floor(-8.333) = -9           System.out.println(Math.floorDiv(x, y));      }  }  

Test it Now

Output:

-9

Example 3

  public class FloorDivExample3  {      public static void main(String[] args)       {          long x = 6754883;          int y = 0;          // Second argument is zero, Output is Airthmetic Exception           System.out.println(Math.floorDiv(x, y));      }  }  

Test it Now

Output:

Runtime Error:  Exception in thread "main" java.lang.ArithmeticException: / by zero  at java.lang.Math.floorDiv(Math.java:1052)  at floorDivExample1.main(floorDivExample1.java:8)

Example 4

  public class FloorDivExample4  {      public static void main(String[] args)       {          long x = 2148;          long y= -1;          // Input positive value and -1, Output first argument           System.out.println(Math.floorDiv(x, y));      }  }  

Test it Now

Output:

-2148
