0.1 + 0.2 != 0.3 is the joke. The reality is that floating-point math underlies your prices, your timestamps, your machine learning, your physics, your everything -- and the bugs it produces don't look like bugs. They look like 'a customer was charged $0.01 too much,' 'this report total is off by a penny,' and 'the test is flaky.' Knowing the rules saves you from chasing ghosts.
