Posit numbers make more efficient use of the bits representing real numbers than do conventional IEEE floating point numbers. This post explains what posits are, how their bits are interpreted, their dynamic range, etc.| John D. Cook
How to handle floating point exceptions such as 1.#IND, 1.#INF, nan, and inf| John D. Cook
Knowing the details of how floating point numbers are implemented can help you avoid problems with them.| John D. Cook | Applied Mathematics Consulting
For any x, the behavior of multiples of x mod 1 is easy to classify. The powers of x mod 1 are more interesting. We give examples of different behavior.| John D. Cook
Most numbers that are representable as machine integers are not exactly representable as floating point numbers.| John D. Cook
