EDOM
Prototype
#include <errno.h>
#define EDOM implementation-defined
Description
The EDOM
macro expands to a constant value that is stored in errno
after a domain error occurred. This type of error occurs
when a mathematical function argument is outside the domain over
which the mathematical function is defined.
For example, a domain error occurs for acos
arguments not in the range
[-1,+1].
