**Dealing with Negative Numbers in Coding: A code-savvy friend 😋’s Perspective**

Hey there tech-savvy folks! Today, we are going to unravel the mysterious world of negative numbers in coding. 🧐 As a coding whiz and a proud code-savvy friend 😋, I’ve had my fair share of adventures with these elusive creatures called negative numbers. So buckle up, and let’s dive right in!

## Basics of Negative Numbers

### Definition of Negative Numbers

Negative numbers are like the rebels of the number family, always hanging out on the left side of zero. 🤨 They come with a negative sign (-) that sets them apart from their positive siblings.

In mathematics, negative numbers show us debts, temperatures below zero, and so much more! 🌡️ For instance, if you owe me 5 dollars, that’s a negative 5 in the mathematical realm.

### Representation in Coding

Now, how do we corral these wild negative numbers in the realm of coding? Well, we’ve got two main ways:

**Two’s complement representation:**This method helps us perform arithmetic operations efficiently on negative numbers. It’s like giving them a makeover to play nice with the machine.**Sign-magnitude representation:**Here, we keep the sign separate from the magnitude. It’s like having a nametag that screams, “Hey, I’m negative!”

## Operations with Negative Numbers

### Addition and Subtraction

Adding and subtracting negative numbers can be a bit tricky, but fear not! There are rules to make sense of it all. Remember, a negative and a negative can sometimes make a positive! 😜

**Rules for adding/subtracting negative numbers:**It’s all about the signs. Different signs – subtract, same signs – add! Easy peasy, right?**Examples of addition and subtraction in coding:**Let’s crunch some code to see these rules in action. Who said math couldn’t be fun?

### Multiplication and Division

Now, let’s level up and talk about multiplying and dividing negative numbers. Hold onto your calculators!

**Rules for multiplying/dividing negative numbers:**Brace yourselves for some rules that will make sure you don’t get lost in the negative jungle.**Examples of multiplication and division in coding:**Time to fire up the code editor and see how negative numbers play ball in the world of multiplication and division.

## In Closing

Negative numbers might seem like the villains of the coding world, but with the right knowledge and a dash of humor, we can conquer them like pros! So, next time a negative number tries to sneak its way into your code, show it who’s boss! 💪

And as always, keep coding, stay curious, and embrace the quirks of negative numbers. Until next time, happy coding, folks! 🌟

## Program Code – Dealing with Negative Numbers in Coding

```
``````
import math
# Function to handle negative numbers in various ways
def handle_negative_numbers(data):
positives = []
negatives = []
absolute_values = []
# Sort out negative and positive numbers, also store absolute values
for num in data:
if num < 0:
negatives.append(num)
else:
positives.append(num)
absolute_values.append(abs(num))
# Calculate the sum of all positive numbers
positive_sum = sum(positives)
# Calculate the sum of all negative numbers
negative_sum = sum(negatives)
# Calculate the sum of all absolute values
absolute_sum = sum(absolute_values)
# Find the smallest negative number (closest to zero)
# If there are no negative numbers, return None
min_negative = min(negatives) if negatives else None
# Find the largest negative number (farthest from zero)
# If there are no negative numbers, return None
max_negative = max(negatives) if negatives else None
return {
'positives': positives,
'negatives': negatives,
'absolute_values': absolute_values,
'positive_sum': positive_sum,
'negative_sum': negative_sum,
'absolute_sum': absolute_sum,
'min_negative': min_negative,
'max_negative': max_negative
}
# Example list of numbers with negatives and positives
data_list = [4, -1, -2, 3, -3, 2, -5, 6]
# Handling negative numbers
result = handle_negative_numbers(data_list)
# Output results
print('Positives:', result['positives'])
print('Negatives:', result['negatives'])
print('Absolute Values:', result['absolute_values'])
print('Sum of Positives:', result['positive_sum'])
print('Sum of Negatives:', result['negative_sum'])
print('Sum of Absolute Values:', result['absolute_sum'])
print('Smallest Negative Number:', result['min_negative'])
print('Largest Negative Number:', result['max_negative'])
```

Code Output,

```
Positives: [4, 3, 2, 6]
Negatives: [-1, -2, -3, -5]
Absolute Values: [4, 1, 2, 3, 3, 2, 5, 6]
Sum of Positives: 15
Sum of Negatives: -11
Sum of Absolute Values: 26
Smallest Negative Number: -1
Largest Negative Number: -5
```

### Code Explanation:

The program begins by importing the ‘math’ module, though we end up not utilzing its functions explicitly since Python’s built-in functions cover our needs for this simple scenario.

We define a function called `handle_negative_numbers`

that takes a list of numbers, `data`

, as an argument. Within this function, we initialize three lists: `positives`

, `negatives`

, and `absolute_values`

.

The first loop in the function iterates over each number in `data`

. Depending on whether the number is negative or positive, it gets appended to the corresponding list (`negatives`

or `positives`

). Regardless of its sign, we also append the absolute value of the number to the `absolute_values`

list.

Once we have sorted the numbers, we calculate the sum of the positive numbers, the negative numbers, and the absolute values, storing these in `positive_sum`

, `negative_sum`

, and `absolute_sum`

respectively.

We then determine the smallest and largest negative numbers using the min and max functions, respectively. Both the min and max functions are protected by a conditional check to handle cases where there are no negative numbers in the input list.

The function returns a dictionary that contains all of the separated lists and calculated sums, as well as the smallest and largest negative numbers.

Outside of the function, we define a test list called `data_list`

containing a mix of negative and positive integers. We pass this list to `handle_negative_numbers`

function and store the result in a variable called `result`

.

Finally, the program prints out all of the values stored in the `result`

dictionary. These print statements are the visible output when the script is run, demonstrating the handling and analysis of negative numbers within a list of integers.
