There's definitely an information war that needs to be won. That D has been around for 15-odd years and is still considered an emerging language is something of a problem.

I linked my DConf talks on a games industry forum, and the first response was that "It looks like a poor man's Rust". A notion I quickly dispelled, but it's a mindset that needs solid, linkable examples to work against. The talk I'm hoping to hold at GDC Europe in August will have some examples to that effect (they still haven't got back to me with confirmation). I'll need to make that more visible than slides/video once the talk is done.

Echoing the need for decimal support. I won't use it myself, but I know it's critical for finance.

The problem is that D is targeted as a multi-paradigm systems programming language, and while it's largely successful at that, the GC doesn't fit in with that domain by nature of its existence.

There's no problem with _having_ a GC, it just shouldn't be the default case for what's meant to be a systems language, especially when language and standard library features become dependent upon it.

But I digress: we've had this debate before, we're having it now, and we'll keep having it well into the future :-)

Do C, C++, Java, Go, or Rust have a standard decimal type? -- Andrei

Writing GC's issues off as pressure from reddit would be an understatement. -- Andrei

These are only a part of our competition. -- Andrei

C/C++: not really
Java: https://docs.oracle.com/javase/tutorial/i18n/format/numberintro.html
Go: Two proposals as of last year https://forum.golangbridge.org/t/what-is-the-proper-golang-equivalent-to-decimal-when-dealing-with-money/413/8
Rust: nope
PHP: Has stuff, but we REALLY don't want to go around copying them

So where is it used? PHP, Java and C# the most. What are the languages used in making e-commerce stuff? Them.

Please, elliminate GC.
This also hurts the open source community. Why would I write/opensource a high performance library if I know that projects like AAA games are not going to use it anyway due to GC in D? On the other hand if I can write a library that guarantees to not use and not need garbage collector then even C and C++ projects can use it.
With GC, D doesn't play nice with existing C/C++ code.

Quality is an issue, but I thing a bigger problem for adoption is just the time it takes a new user to set the dev environment up. If you look at those pages:
https://wiki.dlang.org/Editors
https://wiki.dlang.org/IDEs
most of the tools use dcd, dscanner and dfmt to provide the most important features like auto-completion, autoformatting etc.
The problem is that dcd, dscanner and dfmt are not bundled together so it takes a long time to actually install all this together. Note that discovering what is what also takes a lot of time for a new user.
I tried to do this recently and it took me 2 days before I found a combination of versions of dcd, dscanner, dfmt, dub and an IDE that work together correctly on Windows. My example is probably extreme but is a lesson.

May I suggest bundling the official tools with dcd, dscanner, dfmt and dub to create a Dlang-SDK.

Then the user would only have to install
- Dlang-SDK
- An editor
And everything would work. This would reduce the time from a few hours (with a very large variance) to 30 minutes. Then maybe people who try D in their free time without being strongly indoctrinated by Andrei will not quit after 30 minutes. :)

That's about formatting numbers, not about a decimal type.

http://docs.oracle.com/javase/8/docs/api/java/math/BigDecimal.html

is more like it.

With java 7 there is the big decimal library in java:

Kind regards

Apparently there's a spec: http://speleotrove.com/decimal/decarith.html
