Writing generic numeric code in .NET is difficult, because .NET generics do not support constraints specifying that a type has to support certain numeric operations. In this article, we look how to solve the problem in F#. Using static member constraints, it is possible to write simple generic calculations and using the INumeric interface, we can capture numeric operations for a type and use them when implementing complex types such as a matrix.

In this article, we look at defining custom numeric types in F#. We'll create a numeric type representing numbers in a clock artihmetic (with base 5) and we'll see how to define custom operators, numeric literals and how to support F# PowerPack matrices.

Following my back-to-back talks with the UK Developers Group and NxtGenUG Southampton, I just like to say thanks those guys for having me, it’s been a great pleasure For anyone interested, here are the links to the slides and the source code I used for the demo.

Gordon has a blog post on F# agents with timeouts In my previous post , I showed a code snippet with a very simple F# agent console application. You run the app from the console, and every time you enter a line of text, it generates a new message and posts it to the message queue of an F# agent. An agent... Click here for the full article...
