here is the code that I have so far and I can not seem to get it to work properly it is return 1 for any number that is entered. Any help that you can give me would be greatly appreciated. Thanks

#include <stdio.h>



double square_root(double low, double high);

int main(void)
{
    float number;
    double root;
    
    printf("Enter a number to compute the square root of.\n");
    scanf("%f", &number);
    
    root = square_root(1, number);
    
    printf("The square root of %.3f is about %.3lf\n", number, root);
    
    system("PAUSE");
    return 0;
}

	double square_root(double low, double high)
{
    float mid;
    
    mid = (high + low) / 2;
	//x(n+1) = 1/2( x(n) + a / x(n) )

    //Base Case
    if((mid*mid) == high)
        return mid;

     //Stops when the high and low numbers are within 0.001 of one another.   
    if((high - low) < 0.001)
        return mid;
    
    if((mid*mid) > high)
        //return square_root(low, mid);
        
    return square_root(mid, high);
}
