Talk:C mathematical functions

message: Should the C99 math.h functions be included here as well? E.g. fabsf, fabsl, etc. These functions all deal with floats and long doubles -- cmath is not required for that. --204.69.182.1 17:42, 28 July 2006 (UTC)

thread_title:  C99 functions. 

message: C++'s cmath is different from math.h. In particular, cmath puts the functions in the std namespace and uses overloading so that abs(-1.0) does the Right Thing rather than requiring the user to call fabs(-1.0) for doubles and abs(-1) for integers. The page should reflect that. —Ben FrantzDale (talk) 17:46, 23 November 2008 (UTC)
replies: text: You are correct.  The C++ cmath does not define all of the functions from C99, plus it has abs, div, labs, and ldiv functions.  In addition C++ overloads the math functions so they are type generic.  In effect the libraries are similar on the surface but are actually completely different.  This may not have obvious consequences to your everyday programmer but I think the article needs to reflect this.  Unfortunately I cannot point to a source that gives a good rundown of the differences.  74.194.24.44 (talk) 09:27, 20 September 2009 (UTC)

message: :Based on Talk:C standard library#Pages for each function and WP:NOTMANUAL
The following pages essentially discuss the same topic of C mathematical functions: math.h, casinh, div (C), complex.h, fenv.h, tgmath.h, ccos, cimag, carg, atan2, frexp, ldexp, log (C), acos (C). I propose to cleanup these pages by removing the material that fails WP:NOTMANUAL and by merging the remains into C mathematical operations.1exec1 (talk) 21:03, 8 October 2011 (UTC)
replies: text: Oppose merge of atan2. If you read that article, you will see that it is about atan2 as a mathematical function, and its implementation in multiple programming languages. The C function of that name is mentiond only in passing. Gandalf61 (talk) 22:19, 8 October 2011 (UTC)
replies: text: I agree. atan2 is present in some form in many systems, not just C descendants, and mathematically, it is the true Cartesian-to-angle function which  tan-1 is not. It deserves to be discussed independently of C, or even programming, as it is now. — Unbitwise (talk) 23:00, 8 October 2011 (UTC)
replies: text:  Oops, sorry about that. atan2 certainly shouldn't have been in that list.1exec1 (talk) 23:11, 8 October 2011 (UTC)

so,please someone help meMadhusudan(talk) 05:40, 19 October 2011 (UTC)

message: I think that prototypes as in  are not useful because we don't completely explain these functions. Also, complete documentation is enabled one click away in an external page. I've asked the same question at Talk:C standard library, but got no user input. 1exec1 (talk) 09:47, 10 November 2011 (UTC)
