Binary-arithmetic Memes

ChatGPT confidently declares that 9.11 - 9.9 = 0.21, which is technically correct... if you're doing math in a universe where computers don't exist. But then someone says "use python" and suddenly we get -0.79 because floating-point arithmetic said "let me introduce myself." The real kicker? ChatGPT then explains the floating-point precision issue like a professor who just realized they wrote the wrong answer on the board but needs to save face. "Small precision errors" is putting it mildly when your subtraction is off by a whole sign and an order of magnitude. This is why we can't have nice things like accurate financial calculations without using Decimal libraries. Binary fractions gonna binary fraction. 🤷
