I agree here too. Most people cope just fine with floating point. Usenet magnifies the number of people reporting issues (due to testing for equality or using them for currency and so on), but there is almost certainly a silent majority who either just figure it out or understand how to use floats from the get-go. But there is an issue, however small, and it's due, largely, to the fact that people can't see the representation of floats very well. All sorts of things conspire (for the very best of engineering reasons) to make it hard to see what actual value you are holding. Yes, people have been doing arithmetic for thousands of years, but they've usually done it by manipulating the representation themselves. The "behind the scenes" effects of floating point are a relatively new phenomenon though. > But one thing is certain: very few people, Jon Ribbens being one of them, > expects 1/3 to return 0.
