Example of floor() and ceil() functions in c

/* C program to demonstrate example of floor and ceil functions.*/
 
#include <stdio.h>
#include <math.h>
 
int main()
{
    float val;
    float fVal,cVal;
 
    printf("Enter a float value: ");
    scanf("%f",&val);
 
    fVal=floor(val);
    cVal =ceil(val);
    printf("floor value:%f \nceil value:%f\n",fVal,cVal);
    return 0;
}

Output

    Enter a float value: 123.45
    floor value:123.000000 
    ceil value:124.000000
