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:

5 Feb 2021 Should I use the header ctgmath? It automatically includes cmath and ccomplex. It has some predefined macros. Should its inclusion affect my

Any sufficiently complicated C program contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of C++. marcosdumay 16 days ago Yes, but it's most of the good 1/5 of it, with just a little bit of the atrocious 1/3, and the rest taken from the "who cares" 7/15. If you’re unable to edit the “tgmath.h” file, you can wait for the 20.9 release where we’ll have this fixed, or add the following to your code, before including “tgmath.h”. #define cfabs cabs #define cfabsf cabsf #define cfabsl cabsl It seems that tgmath.h is not available on Darwin: $ gcc-dp-4.2 -std=gnu99 -Wall -o complex complex.c complex.c:3:20: error: tgmath.h: No such file or directory $ gcc-dp-4.2 --version gcc-dp-4.2 (GCC) 4.2.0 20060729 (experimental) There is no file tgmath.h provided with the compiler that could be installed (I checked revision 120754).

Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C library. The C standard library provides macros , type definitions and functions for tasks such as string handling, mathematical computations, input/output processing, memory management , and several other operating system services.

Hello, Two questions related to floating point support: What C compilers for the wintel (MS Windows + x86) platform are C99 compliant as far as and are concerned? tgmath.h --- type-generic macros SYNOPSIS #include DESCRIPTION The functionality described on this reference page is aligned with the ISO C standard.

The C ctype.h header file declares a set of functions to classify (and transform) individual characters. For example, isupper() checks whether a character is uppercase or not.
