Java.lang.StrictMath.ceil() Method
Description
The java.lang.StrictMath.ceil() method returns the smallest (closest to negative infinity) double value that is greater than or equal to the argument and is equal to a mathematical integer.This include these cases −
- If the argument value is already equal to a mathematical integer, then the result is the same as the argument.
- If the argument is NaN or an infinity or positive zero or negative zero, then the result is the same as the argument.
- If the argument value is less than zero but greater than -1.0, then the result is negative zero.
Declaration
Following is the declaration for java.lang.StrictMath.ceil() method
public static double ceil(double a)
Parameters
a − This is the double value
Return Value
This method returns the smallest (closest to negative infinity) floating-point value that is greater than or equal to the argument and is equal to a mathematical integer.
Exception
NA
Example
The following example shows the usage of java.lang.StrictMath.ceil() method.
package com.tutorialspoint; import java.lang.*; public class StrictMathDemo { public static void main(String[] args) { double d1 = 5.3 , d2 = 7.8, d3 = 1.5; // returns the largest double value, greater than or equal to argument double ceilValue = StrictMath.ceil(d1); System.out.println("Ceil value of " + d1 + " = " + ceilValue); ceilValue = StrictMath.ceil(d2); System.out.println("Ceil value of " + d2 + " = " + ceilValue); ceilValue = StrictMath.ceil(d3); System.out.println("Ceil value of " + d3 + " = " + ceilValue); } }
Let us compile and run the above program, this will produce the following result −
Ceil value of 5.3 = 6.0 Ceil value of 7.8 = 8.0 Ceil value of 1.5 = 2.0
