The Decimal Dilemma in Computing

Python can do your math homework in seconds, but here's the twist nobody tells you:

when you type 0.1 plus 0.2, you don't get 0.3. You get 0.30000000000000004. This isn't a bug,

it's how computers think in binary. They can't perfectly represent simple decimals we use

every day. That's why you never compare floats with equals signs in real code.

Instead, programmers check if numbers are close enough within a tiny tolerance.

This same limitation affects everything from your banking app to NASA's calculations. The computers running

our world are constantly working around their own mathematical blind spots. Wild how we trust

machines that can't even add decimals correctly, yet they still power literally everything.
