More people need to learn to use Rational types. A pretty large majority of the numbers that people care about in real life can easily be represented by a ratio of integers, and they allow math with perfect precision.

Or just BigDecimal or an equivalent if rational types aren't easy to use in your language (e.g if you'd have to literally enter the denominator and numerator).

Someone posted this article a while back that goes into more detail on some alternatives, as well as contains one of the best and most intuitive explanations of floating point that I've ever read.
