Empty C headers. The headers , , , and do not contain any content from the C standard library and instead merely include other headers from the C++ standard library. The use of all these headers is deprecated in C++. In a C program, unless you're using the macro to call this function, scalbn always takes a double and an int and returns a double, and scalbln always takes a double and a long and returns a double.

3 # Every other C header, each of which has a name of the form name.h, behaves as if each name placed in the standard library namespace by the corresponding c name header is placed within the global namespace scope 2007-02-02 This header defines macro functions that correspond to the functions in , but which can take other non-floating point types as arguments: Every function in that takes at least one double as argument (except modf) is defined in as a macro with the same semantics but taking generic parameters instead: The header tgmath.h includes the headers math.h and complex.h and defines a number of type-generic macros. This requires the compiler that is designed to support C99. Use of the macro invokes a function whose corresponding real type and type domain are determined by the arguments for the generic parameters.

Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C c documentation: Getting started with C Language.

Include the standard header to define several families of generic functions.A generic function has the same name for two or more distinct parameter lists, as in: In a C program, unless you're using the macro to call this function, pow always takes two double values and returns a double value. If you use the pow() macro, the type of the argument determines which version of the function is selected.
