C maths

Let's see a simple example of math functions found in math.h header file.

#include<stdio.h>
#include <math.h>
int main(){
    printf("\n%f",ceil(3.6));
    printf("\n%f",ceil(3.3));
    printf("\n%f",floor(3.6));
    printf("\n%f",floor(3.2));
    printf("\n%f",sqrt(16));
    printf("\n%f",sqrt(7));
    printf("\n%f",pow(2,4));
    printf("\n%f",pow(3,3));
    return 0;
}
