Java Floor() Method

Description

The method floor provides the main integer that is less than or equivalent to the argument. floor() returns the twice value that is fewer than or equal to the argument and is equal to the adjacent mathematical integer. Note: If the argument is Integer, then the consequence is Integer. If the argument is NaN or an infinity or optimistic zero or negative zero, then the result is similar to the argument.

Syntax

This method has the following variants:

double floor(double d)
double floor(float f)

Parameters

Here is the detail of parameters −

• A double or float primitive data type.

Return Value

• This method returns the largest integer that is less than or equal to the argument. Returned as a double.

Example

public class Test { 

   public static void main(String args[]) {
      double d = -100.675;
      float f = -90;

      System.out.println(Math.floor(d));
      System.out.println(Math.floor(f)); 

      System.out.println(Math.ceil(d));
      System.out.println(Math.ceil(f));
   }
}

This will produce the following result:

Output

-101.0
-90.0
-100.0
-90.0
