Java Ceil() Method

Description

The technique ceil provides the negligible integer that is better than or equivalent to the argument. ceil() returns the twice value that is better than or equivalent to the argument and is equivalent to the nearest mathematical integer. Note: If the argument is a figure, then the result is Integer. If the argument is NaN or an infinity or constructive zero or negative zero, then the product is the same as the argument.

Syntax

This method has the following variants:

double ceil(double d)
double ceil(float f)

Parameters

Here is the detail of parameters −

• A double or float primitive data type.

Return Value

• This method returns the smallest integer that is greater 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.ceil(d));
      System.out.println(Math.ceil(f)); 

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

This will produce the following result −

Output

-100.0
-90.0
-101.0
-90.0
