Basically Free Money

Oh, the absolute JOY of floating-point arithmetic in JavaScript! Nothing screams "professional financial software" quite like receiving 3 dimes and somehow ending up with $0.30000000000000004 because JavaScript's Number type decided to have an existential crisis about decimal representation. It's like asking for exact change and getting handed the mathematical equivalent of "close enough, right?" Binary floating-point numbers can't represent 0.1 precisely, so when you do basic math, you get these delightful microscopic errors that haunt your financial calculations. But hey, that extra 4 quadrillionth of a cent? That's YOUR bonus for trusting JavaScript with money calculations. Stonks! 📈
