ceil function in C programming language

In this tutorial, we will learn about ceil function in C programming language

In the C Programming Language, the ceil() returns the nearest integer value which is greater than or equal to the value of floating point passed value.

Declaration

Syntax

The syntax of the ceil() function in the C programming Language

double ceil(double x);

parameters or Argument

x is the parameter or argument of this , x is a floating point value.

Return value

when the value for x is passed, this is returns the ceil value of x

Required Header

include <math.h>

ceil function in C

Example

program

The following example explains the usage of ceil() function

//Example for ceil math function in C language
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main()
{       //Define temporary variables
    double a=12.1,b=12.9,c=-12.1,d=-12.9;
     //Calculate and display ceil value for given value
        printf("ceil value of a: %f\n",ceil(a));
        printf("ceil value of b: %f\n",ceil(b));
        printf("ceil value of c: %f\n",ceil(c));
        printf("ceil value of d: %f\n",ceil(d));
    return 0;
}

When the above program is compiled and run, it will produce the following result

ceil value of a: 13.000000

ceil value of a: -12.000000
