math functions in C# ???

Got it. I typed System.Math and intellisense did not find it, so I assumed it did not exist. I need to get Visual Assist on here, pronto.

But I've read somewhere(dont remember where i read) that VA is not so stable for vstudio.net, I guess the beta status explains that a bit. Cheers Kannan

Thanks for the info :) Christian Graus wrote: VA does the case correction, C# does not by itself. Thats the impression I got. I must say, it strikes me as silly that that is the case however. It means that whatever is doing the case correction is not built into the editor, but actually into the bit that each language provides to plug-in to the editor. Or at least, so it would seem. After being used to it in VB since 16-bit VB3, it certainly takes a bit of getting used to :) -- David Wengier Sonork ID: 100.14177 - Ch00k

In both C++ and C# SomeClass and someclass is two different classes because the languages are case sensitive. Because of that I think it would be *very* dificult to make C++ and C# correct the case for you. I mean, if you have 2 int's called IntOne and intOne, and you just typed intone, which one should the IDE select? ;) - Anders Money talks, but all mine ever says is "Goodbye!"

This is a very good point, which in fact I didnt know about C#. -- David Wengier Sonork ID: 100.14177 - Ch00k

This is a problem I have with VA at work - our class library includes try/catch wrappers which specify a HRESULT called hResult. Every time I type hResult, it turns it all to capitals, as it does not expand the macro and see the variable name. If VB is not case sensitive ( and how gay is THAT ? ), then the IDE isn't doing any case correction at all, it's simply ignoring it - right ?

I know, thanks, I just had not reinstalled it just yet after all the hassles I had getting .NET installed at all. Intellisense is working, Matk is a class. How gay - I have to type Math.Min when I want to min something ? I suppose I could type Math m; m.Min, but it still sucks. C# is pretty cool though, but I need to do some testing. I am convering an image library I wrote using GDI+ in C++ and I think initially it is orders of magnitude slower doing exactly the same thing as the C++ code I wrote prior.

Okay, I know I will get flamed for this, but why prefix private members with anything? I dont expose variables publically, but use property methods that are public, so I never have public variables. As for private methods, why would you prefix them at all? :confused: -- David Wengier Sonork ID: 100.14177 - Ch00k

oops, guess I shouldn't be replying to messages after I wake up from sleeping on a long ride home. I should have said private variables; because in many cases in my code a private variable would have a public get or get/set property defined for it.

Funny how I lile the fact that I have to type in the class name first and then it's method to use it, while you think it is naff. I guess I like the structure of it, it helps to structure the app in my head better than if all I had to type was Min. Just FYI, and you probably do know this, you can instead of doing
Math mdousing m = System.Math;. Has much the same affect, but it is across your whole class, not just a procedure.

I dunno what VB offers, but in C++, math is a library which provides these functions, so I am just used to the language offering maths facilities without the need for my code to be full of Math.

I hate macros, but the inline keyword is a suggestion which the compiler is free to ignore, so a macro is the best way of knowing for sure the code is running in place.
