C :: Cannot Get Out Of Loop - Stuck With Updating Variables

Code:
#include<stdlib.h>#include<stdio.h>
#include<unistd.h>
#include<math.h>
int main(void)
{
double N, NG, LG, epsilon, root; // setting all variables to type double

[Code] .....

The goal is to create a program to calculate the square root of a number provided by the user to an error tolerance 0.005

Looking around i fond the Code: fabs(NG - LG) < epsilon); section that was very similar to what i was using, but if this is better im down for that.

My issue, from what i can see, is the updating of the values of LG. if the test for error tolerance fails then LG needs to take on the value of the results of NG.

Now I am not 100% that is the point of failure due to the fact the script does calculate the root properly, but it never exits the program once it reaches the tolerance level.

Code: imac:ENG-3211 user$ ./hw_4_1

Please enter the number you wish to find the square root: 4

4.00 2.500
4.00 2.050
4.00 2.001
4.00 2.000
4.00 2.000
4.00 2.000
4.00 2.000
4.00 2.000
4.00 2.000

And it continues forever until i manually break the program even though the answer was found, in this example, on the 4th loop.
