C Program To Find Floor and Celing Value Using If and Else

#include <stdio.h>
int main()
{
    float num;
    printf("Enter a number:\n");
    scanf("%f", &num);
    if (num < 0)
    {
        if (num == int(num))
            printf("The celing value is %.0f. \nThe floor value is %.0f.", num, num);
        else
        {
            printf("The celing value is %d.\n", int(num + 1));
            printf("The Floor value is %d.", int(num));
        }
    }
    else
    {
        if (num == int(num))
            printf("The celing value is %.0f. \nThe floor value is %.0f.", num, num);
        else
        {
            printf("The celing value is %d.\n", int(num));
            printf("The Floor value is %d.", int(num - 1));
        }
    }
}

OUTPUT 1

Enter a number:
-5.2
The Celing value of give number is -5.
The floor value of given number is -6.

OUTPUT 2

Enter a number:
-5
The Celing value of give number is -5.
The floor value of given number is -5.

OUTPUT 3

Enter a number:
5.6
The Celing value of give number is 6.
The floor value of given number is 5.

OUTPUT 4

Enter a number:

The Celing value of give number is 4.

The floor value of given number is 4

C Program To Find Celing And Floor Calue Using Math.h
