C Program Language (Math.h Function - Fabs,Floor,Ceil)

These program is all about the functions fabs, floor and ceil. Discover how those function works and the importance in the C programming language. At this time also I will be using math.h which is very important in solving mathematical operations.
The problem: Show the value of x after each of the following statement is performed.


a. x =  fabs (7.5)
b. x = floor  (7.5)
c. x = fabs (0.0)
d. x = ceil  (0.0)
e. x = fabs (-6.4)
f. x = ceil (-6.4)
g. x = ceil (-fabs ( -8 + floor (-5.5))) 


Observe the output below.

The complete codes for the output.

#include<stdio.h>
#include<conio.h>
#include<math.h>
#include<stdlib.h>
main()
{
float x;
printf("a) The Value of X is %.2f\n",-fabs(-7.5));
printf("b) The Value of X is %.2f\n",floor(7.5));
printf("c) The Value of X is %.2f\n",fabs(0.0));
printf("d) The Value of X is %.2f\n",ceil(0.0));
printf("e) The Value of X is %.2f\n",fabs(-6.4));
printf("f) The Value of X is %.2f\n",ceil(-6.4));
printf("g) The Value of X is %.2f\n",ceil(-fabs(-8)+(floor(-5.5))));
getch();
