# Question 1:
# The international standard for floating-point representation is
# called the "IEEE 754 Standard for Floating-Point Arithmetic."
# Question 2:
# 32-bit and 64-bit formats are the most widely used ones in practice.
# Question 3:
# My computer supports all these formats
import numpy as np
supported_formats = np.finfo(np.float32).bits, np.finfo(np.float64).bits
print(f"Your computer supports the following floating-point formats: {supported_formats}")
# Question 4:
# Using the Pandas multiplication operator (df['Number1'] * df['Number2'])
# , the result is automatically converted to a floating-point data type.
# On the other hand, when I multiply the numbers using the normal Python
# multiplication operator (num1 * num2), the result remains an integer
# data type.
# Question 5:
# The size of a floating-point number in memory is primarily determined
# by the data type and not the actual value it represents. So the size
# of a Python floating-point number does not change as it gets larger.

# Name three practical differences between Python strings and bytes.
# Using sys.getsizeof, see how the sizes may be different.
# Do emoji change this answer?
# Encoding
# Strings are created using Unicode character points.
# While bytes are used to represent actual bytes in memory, which can be encoded using ASCII or UTF-8.
# Usage
# Strings are usually used to represent text.
# While bytes are used to represent binary data.
# Memory Size
# Strings take up more memory than bytes, because they are Unicode-based and can contain any character.
# While bytes are limited to binary data.
