digitalmars.D.learn - limits for numeric types

Where can I get values for min/max values for D numeric types,
like what is available in limits.h and float.h for C/C++?

My efforts have demonstrated that using a search engine for D
related topics still has a way to go.

Top results for the search "dlang limits numeric types" on Google.

1. Regulation D Wikipedia entry
2. Primitive Data Types (The Java Tutorials) - Oracle
3. Regulation D - Pacific Trust Bank
4. Numeric Type Overview - MySQL
5. Built-in-Types - Pyton 2.7.5
6. Regulation D Reserve Requirements (US Federal Reserve)
7. Hottest Numeric Limits Answers (Stack Overflow)
8. Regulation D - Tyndall Federal Credit Union
9. limits.conf() - Linux Man Page

Googling "dlang numeric limits" does turn up a single D reference

for.

Literally type:

int.max
int.min
long.max
long.min

etc etc etc. The one that's weird is float.min_normal I think.

There's a list here:

Thank you very much.
Now, is there any way to get Google to find my question/your
answer if someone searches for "dlang numeric limits"?

Cheers,
Craig

Oddly enough, using Bing or Yahoo (same engine maybe?) return
better results than Google.  I guess I need to ween myself off my
Google dependency.

Good idea! I became a Bing guy a couple years ago and only go to 
google for those rare times when the bing results just suck. I 
find bing to be a much faster website too. (which is weird, they 
do these fancy backgrounds that you'd think would make it slow, 
but the actual search box works before the bg is loaded so it 
doesn't matter)

I am going to feel dirty using a Microsoft site, but I will just
have to get used to it!

I travel to China frequently and half the time Google is
completely useless there (oddly enough at other times it works
perfectly).  The problem with Bing in China is that tends to
return only Chinese results to my English searches.
Interestingly, Yahoo seems to work the best in China (for English
language searches at least).

I usually use the integrated search feature in my browser, so I
usually don't have to worry about the fancy backgrounds.

Yes, get the text, "numeric limits" onto the page.

Though, "dlang max int" seems to work just fine.

Could you expand on this part a bit.  Is there a way to tell the
Google search engine, hey I searched for this, you gave me these
links, but here is the one I wanted.

Sorry, replied too early in the morning.  Now I understand what
you are saying, to add numeric limits to the D site.  I may give
that a try.

Don't use float.min/double.min/real.min. I have opened a bug 
report:

Take a look at this:

	http://dlang.org/property.html

D type names have built-in properties: int.max, real.max, float.max,
etc.. No need to resort to an external file to define all these, since
the compiler already knows them in the first place!

I have the following chapters, especially the first one is decidedly brief:

   http://ddili.org/ders/d.en/types.html

   http://ddili.org/ders/d.en/floating_point.html

No, I could not come up with search terms that would find them. :(
