Java Math.floor() method

The java.lang.Math.floor() is used to find the largest integer value which is less than or equal to the argument and is equal to the mathematical integer of a double value.

Syntax

Parameter

Return

  This method returns largest floating-point value that is less than or equal   to the argument and is equal to a mathematical integer of a double value.  

If the argument is positive or negative double value, this method will return the Floor value.
If the argument is NaN, this method will return same argument.
If the argument is Infinity, this method will return Infinity with same sign as the argument.

Example 1

  public class FloorExample1  {      public static void main(String[] args)       {          double x = 94.69;          // Input positive value, Output floor value of x          System.out.println(Math.floor(x));      }  }  

Test it Now

Output:

94.0

Example 2

  public class FloorExample2  {      public static void main(String[] args)       {          double x = -39.28;          // Input negative value, Output floor value of x          System.out.println(Math.floor(x));      }  }  

Test it Now

Output:

-40.0

Example 3

  public class FloorExample3  {      public static void main(String[] args)       {          double x = 0.0;          // Input positive zero, Output positive zero           System.out.println(Math.floor(x));      }  }  

Test it Now

Output:

0.0

Example 4

  public class FloorExample4  {      public static void main(String[] args)       {          double x = -7.0 / 0;          // Input negative infinity, Output negative infinity          System.out.println(Math.floor(x));      }  }  

Test it Now

Output:

-Infinity
