Output

Sure! Below is the C implementation of the provided Python `my_sqrt` function using the Babylonian method. The function `my_sqrt` takes two `float` parameters: `number` (the number you want to find the square root of) and `precision` (the desired precision level). It returns the square root of the given number as a `float`. ### C Implementation

### Explanation 1. **Include Necessary Headers:** - `stdio.h` is included for input and output functions. - `math.h` is included for mathematical functions like `fabsf` (floating-point absolute value) and `NAN` (Not a Number). 2. **Function `my_sqrt`:** - **Edge Case Handling:** - If the input `number` is negative, the function returns `NAN` since the square root of a negative number is not a real number. - If the `number` is `0` or `1`, the function returns the `number` itself as the square root. - **Initial Guess:** - The initial guess for the square root is set to half of the input number. - **Babylonian Iteration:** - The loop continues updating the guess using the formula `guess = (guess + number / guess) / 2` until the difference between `guess * guess` and `number` is less than the specified `precision`. - **Return Value:** - The function returns the computed square root. 3. **`main` Function:** - Prompts the user to enter a number. - Calls the `my_sqrt` function with the entered number and a predefined precision (`0.0001`). - Checks if the result is `NAN` to handle negative inputs. - Prints the approximate square root of the number. ### Example Usage 
1
2
Enter a number to find its square root: 25
The square root of 25.0000 is approximately 5.0000

1
2
Enter a number to find its square root: -9
Cannot compute the square root of a negative number.
### Notes - **Precision:** The `precision` parameter determines how accurate the result should be. A smaller `precision` value leads to a more accurate result but may require more iterations. - **Performance:** For very large or very small numbers, consider adding a maximum number of iterations to prevent potential infinite loops in cases where convergence is slow. - **Error Handling:** The function currently returns `NAN` for negative inputs. Depending on your use case, you might want to handle this differently, such as returning an error code or using complex numbers. Feel free to integrate this function into your projects or modify it to better suit your specific needs!

Output

Certainly! Below is the C implementation of the provided Python `my_sqrt` function. This C function, `my_sqrt`, takes two `float` parameters: `number` for which the square root is to be calculated, and `precision` which determines the accuracy of the result. The function uses the **Babylonian method** (also known as Heron's method) to iteratively approximate the square root. ### C Implementation

### Explanation 1. **Includes:** - `stdio.h` for input and output functions. - `math.h` for the `fabsf` function, which computes the absolute value of a `float`. 2. **Function `my_sqrt`:** - **Edge Case Handling:** - If the input `number` is negative, the function returns `-1.0f` to indicate an error since the square root of a negative number isn't defined in the realm of real numbers. You can modify this behavior based on your application's requirements (e.g., handling complex numbers). - If the input `number` is `0.0f`, the function immediately returns `0.0f` since the square root of zero is zero. - **Initial Guess:** - Starts with an initial guess of `number / 2.0f`, similar to the Python version. - **Iteration:** - Continues to improve the guess using the Babylonian method until the difference between `guess * guess` and `number` is less than `precision`. - **Return Value:** - Returns the computed square root approximation. 3. **`main` Function:** - Prompts the user to input the number for which the square root is to be calculated and the desired precision. - Calls the `my_sqrt` function with the provided inputs. - Handles the case where the input number is negative by checking if the result is `-1.0f`. - Outputs the result with appropriate formatting. ### Sample Output

Enter a number to find its square root: 25
Enter the precision (e.g., 0.0001): 0.0001
The square root of 25.0000 is approximately 5.0000 with precision 0.0001
### Notes - **Precision:** The precision determines how close the approximation should be to the actual square root. A smaller precision value results in a more accurate result but may require more iterations. - **Error Handling:** The function currently returns `-1.0f` for negative inputs. Depending on your use case, you might want to handle this differently, such as printing an error message or using a different method to represent complex numbers. - **Performance:** For very large numbers or very high precision values, consider implementing safeguards against infinite loops or exceeding maximum iterations. Feel free to integrate this function into your projects and modify it as needed to fit your specific requirements!
