     I'm confident you're trying to help, but you seem not to
have noticed that the question was about C, not about C++.  In
particular, there's no <cmath> header in C.

With all due respect, you apparently did not notice this is a "C"
forum, and should have been posted in a "C++" forum then...

Why? The only C++ content in his message was either quoted from your
inappropriate response, or was part of his explanation of why your
response was inappropriate. Precisely because C++ would be on-topic in
such a forum, such a message would NOT be on-topic there.

That said, I am fully aware that that this is a "C" forum, and as
indicated in my response, I searched with "C" as a parameter.

One of the bigger problems today is that many of the newer compilers
are not strictly "C" systems.

And the website I listed is a C programming support site.

So, if you have a problem with my response, perhaps you should really
take it up with the website referenced.

You posted a C++ answer
to a C question 
in a C newsgroup.

The best part, 
in terms of entertainment value, 
is your claim that it is not your fault.

You may have been aware of it, but nothing you wrote in your response
reflected that awareness, other than the use of C in your recommended
search string. However, your use of STL in that same string negates
that. Since STL is commonly used as an abbreviation for the Standard
Template Library which eventually became a major part (but NOT the
entirety) of the C++ standard library, adding STL to the search
virtually guarantees exclusion of C-specific web sites.

...

No, it's a C and C++ programming site, which like many such sites, does
not do a good job of dealing with the differences between C and C++. In
particular, the particular page you cited documents exclusively the C++
version of the floor() function.

I checked, and most of the pages at that site for other standard library
functions document both the C and the C++ header file name, so it was
just bad luck that the page for floor() does not.

The last paragraph of your original message was written entirely by you.
Neither of the mistakes in that paragraph was the responsibility of
anyone other than yourself, and that paragraph could not have been
written by someone who was, as you claim to have been, 'fully aware that
this is a "C" forum'.

     Then why did you offer a C++ answer?  (As it happens, even
if the O.P. had been using C++ your answer would not have helped;
his problem was not with compilation, but with linking.)

     Not sure what you mean by this, or why it would matter.  If
Compiler X conforms imperfectly to the C Standard, does it then
make sense to answer as if for COBOL?

> And the website I listed is a C programming support site.

     No; the web site's *title* says its about C.  But the site
itself is not!  Here's the code from the page you linked to:

	//Example will output 5.9 rounded down
	#include <cmath>
	#include <iostream>
	
	using namespace std;
	
	int main()
	{
	  cout<<"5.9 rounded down: "<<floor(5.9);
	}

     First, it wasn't very smart of you to offer a link to a
poor-quality web site.  (The site may have other fine qualities,
but for the question at hand its quality is poor.)  Second, your
own text in the body of your own message -- something you can't
blame on a web site -- was a C++ answer, not applicable to C.

     Earlier I wrote that I thought you were trying to be helpful.
I'm starting to doubt myself.

Any system worth using will have some mechanism for distinguishing
exactly what it is trying to compile.

Also, for instructional purposes, including C++ features in "C"
programs invites confusion.
