Hi, your job is to interpret a function f(x) that is implemented in the ./temp7/function.py script. f(x) takes numerical inputs.
All you can do is call f(x) on a value of x by running PYTHON(./temp7/function.py value). 
Try to describe the function implemented by f(x) by running experiments on it. 
You can call the function on multiple inputs at a time by running PYTHON(./temp7/function.py value1 value2 value3 ...). 
You can run the function multiple times on the same input. We encourage testing a large range of values before writing a description. You can test values between [-128 and 128]. 
The output could be noisy and your goal is to find a good simple description of f(x) that explains most of the function behavior. f(x) may combine multiple different operations.
There may be an interval inside the domain where the function behaves differently. If that is the case, describe that interval.
Your description of the function should have three parts. 
First, [DESCRIPTION]: Describe what the function is doing in language. 
[DOMAIN]: What is the domain of the function? Is there an interval where the function displays unexpected behavior? What are the numeric bounds of that interval? What is going on there?
[CODE]: Write python code that approximates the behavior of the function. 
assistant:
Let's start by testing the function with some values to understand its behavior.

COMMAND: PYTHON(./temp7/function.py -128 -64 0 64 128)
user:
Response: Function input - output pairs: (-128, 1) (-64, 1) (0, 1) (64, 1) (128, -1) 

assistant:
It seems that the function returns mostly 1. Let's test the function with some more values to see if we can find a pattern.

COMMAND: PYTHON(./temp7/function.py -100 -50 -25 25 50 100)
user:
Response: Function input - output pairs: (-100, -1) (-50, 1) (-25, 1) (25, 1) (50, -1) (100, -1) 

assistant:
The output seems to toggle between 1 and -1. Let's test more values to further identify the pattern.

COMMAND: PYTHON(./temp7/function.py -75 -10 -1 1 10 75)
user:
Response: Function input - output pairs: (-75, -1) (-10, -1) (-1, 1) (1, 1) (10, -1) (75, -1) 

assistant:
Based on the input-output pairs, it looks like the function returns 1 for most negative and zero inputs, and -1 for most positive inputs. However, there are some exceptions (e.g., -100, 50, 100). To further understand the function and any unexpected behavior, let's test more values.

COMMAND: PYTHON(./temp7/function.py -30 -20 -15 15 20 30)
user:
Response: Function input - output pairs: (-30, -1) (-20, 1) (-15, -1) (15, 1) (20, 1) (30, -1) 

assistant:
Let's test additional values focusing on the interval where we observed the unexpected behavior.

COMMAND: PYTHON(./temp7/function.py -110 -105 -99 49 51 110)
user:
Response: Function input - output pairs: (-110, 1) (-105, 1) (-99, -1) (49, -1) (51, 1) (110, 1) 

assistant:
Based on the obtained input-output pairs, the function appears to have the following properties:

[DESCRIPTION]: The function returns 1 for most negative inputs and -1 for most positive inputs. There are exceptions where positive numbers close to multiples of 50 and negative numbers close to multiples of 100 return -1 and 1, respectively.

[DOMAIN]: The function has a domain of [-128, 128] with unexpected behavior observed for positive values close to multiples of 50 (e.g., 49, 50, 51) and negative values close to multiples of 100 (e.g., -99, -100, -101).

[CODE]:
```python
def approx_function(x):
    if x < 0 and (int(x / 100) * 100 <= x < (int(x / 100) + 1) * 100) or x > 0 and (int(x / 50) * 50 <= x < (int(x / 50) + 1) * 50):
        return -1
    else:
        return 1
```
