How can I improve float precision in Python?

You can use the decimal module for better precision with floating-point arithmetic.

Can you show me an example of using the decimal module?

Sure! Here's a simple example:

from decimal import Decimal

# Using Decimal for precision
num1 = Decimal('0.1')
num2 = Decimal('0.2')
result = num1 + num2
print(result)  # Output: 0.3

What are the advantages of using Decimal over float?

The Decimal type avoids issues with binary floating-point representation, providing exact decimal representation.

Are there any performance drawbacks to using Decimal?

Yes, Decimal can be slower than float due to its precision and additional features, so use it when necessary.
