Money-handling Memes

Ah yes, the classic floating-point precision nightmare strikes again! LeBron apparently set his user balance to exactly 100 dollars, but because he used a double (floating-point) instead of a proper decimal type for monetary values, the database now cheerfully displays $99.99999999999 instead of a clean $100. The facepalm is well-deserved. Rule #1 of financial applications: never use floating-point types for money! Binary floating-point can't accurately represent decimal fractions like 0.1, leading to these delightful rounding errors that'll have your accounting department hunting you down. Should've used BigDecimal, DECIMAL, or literally anything designed for exact decimal arithmetic. Even the GOAT isn't immune to the IEEE 754 curse. Stick to the fundamentals, King. 👑
