What areas of code are you using f# for? [closed]

Answer 1

Places where there are lots of mathematical calculations.

Answer 2

I'm using F# to develop an engine for a turn-based strategy game I'm playing with designing. I've found that F#'s mix of functional and OO programing has let me manipulate the data in the game concisely in ways that would be too complicated in an imperative C# to want to do. It's also pretty natural to separate the state-changing actions from the folds and such that determine how the state should change, which definitely helps keep the code simpler and organized.

The biggest trap I may be falling into in the project is using type annotations of tuples for a couple of data types that are used quite intensively in one of the classes. Using tuples makes for pretty concise code, but I'm not sure that using the type annotation in the signature of the functions that use them is sufficient to maintain readable code in some cases.

Answer 3

Here are some good practical uses of F# and Functional programming from Trauma Pony given as an answer to my similar question.

• Computational fluid dynamics
• Physics processing
• Ray tracing
• Data mining
• Medical imaging
• Control engineering software
• Digital signal processing
• Bioinformatics

In fact, check out this page for a lot more examples of where GPGPU has been used.

Answer 4

1. Scientific works (Mathematical and statistical calculations, visualization, optimization,..)
2. Parallel programming (F# supports asynchronous workflows, Erlang style concurrency, Parallel FX, ...)
3. Language oriented programming (eg. DSLs)
4. Data intensive analysis
5. ...

Answer 5

F# does pretty much everything C#, only easier. It's advanced features mean you end up writing a lot less code. OO syntax is more verbose than the other F# syntax, but it's still better than using C#.

We're using it for web services, ASP.NET MVC sites, daemons,

The question is, where not to use it. Right now that looks to be mainly where tool support is lacking. So, for example, with ASP.NET, the ASPX page inline code is C#, but the controllers and everything else is in F#.

The few places where F# isn't as smooth as it should be I imagine will be worked out in the upcoming releases.

Answer 6

I'm considering using F# for HTML processing because the list pattern-matching syntax fits the problem domain well (Prolog is probably better, but still).
