This article discusses two numeric types that are available in F# PowerPack - BigRational represents arbitrary precision rational numbers and complex represents (floating-point) complex numbers. The types can be nicely used from F# as well as from C#.

This article is the first article of a series where I'll explain some of the F# features that are useful for numeric computing as well as some functionality from the F# PowerPack library.

After a quiet summer season, it is time to look at the upcoming F# talks and courses. If you want to learn about functional and asynchronous programming, F# and more, you may want to come to our training (organized with SkillsMatter), tutorials or some community events.

Asynchronous sequences provide a way to represent asynchronous computation that generates multiple values on demand. This article defines asynchronous sequences, combinators for working with them and "asyncSeq" computation builder. Then it implements several examples including a sequential asynchronous Web Crawler.

More than a year ago, I started working on a writing project done with Manning and MSDN team. The idea was to adapt parts of my Real-World Functional Programming book, add some new practical topics and publish the articles on MSDN under the official F# documentation. I'm happy to announce that the articles, covering ASP.NET, F# asynchronous programming and agents, charting and more are now available on MSDN!
