## 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:
4
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
