ceil() function to get lowest number higher than the input number

ceil()

#include <stdio.h>
int main() {
printf("\nNumber = %.2f", ceil(14.32)); // Number = 15.00
printf("\nNumber = %.2f", ceil(14.52)); // Number = 15.00
printf("\nNumber = %.2f", ceil(14.82)); // Number = 15.00
printf("\nNumber = %.2f", ceil(-14.32));// Number = -14.00
printf("\nNumber = %.2f", ceil(-14.82));// Number = -14.00
return 0;
}

We will get lowest integer higher than the input data by using ceil() function. Output is the nearest integer ( on higher side ) of the number.

#include <stdio.h>
#include <math.h>

int main(void){
float num; // num is declared as float variable
num=17.873;     // data is stored
printf("num = %.4f", ceil(num)); // final output
return 0;
}

The above code will give this output.

num = 18.0000

Example with negative value

#include 
#include 
int main(void){
float num; // num is declared as float variable
num=-17.873;     // data is stored
printf("num = %.4f", ceil(num)); // final output
return 0;
}

Output is here

num = -17.0000
