Why are they called "floating-point numbers"?

Floating-point numbers are called "floating" because the decimal point can float; that is, it can be placed anywhere relative to the significant digits of the number. This gives floating-point numbers the ability to represent a wider range of values than integers.

Here's a quick breakdown:

• Integers have a fixed position (like 5, -11, or 0), and they don't include any decimal places.

• Floating-point numbers (like 2.5 or -9.45) can accommodate decimals, allowing them to represent fractions and more precise values.

To illustrate this in Python, you can see how a floating-point number handles both small and large values:

# Integer value
integer_value = 5

# Floating-point values
float_value1 = 2.5
float_value2 = 0.0003
float_value3 = 123456.78

print(integer_value)  # Outputs: 5
print(float_value1)    # Outputs: 2.5
print(float_value2)    # Outputs: 0.0003
print(float_value3)    # Outputs: 123456.78

This flexibility is particularly useful when performing calculations that require precision, such as in scientific computations or financial applications.

As you're learning about different types of numbers in this Python course, understanding how floating-point numbers work will help you manage calculations accurately.
