Namespaces
namespace	theoretica
	Main namespace of the library which contains all functions and objects.

Macros
#define	TH_MATH_ERROR(F_NAME, VALUE, EXCEPTION)    { errno = theoretica::to_errno(EXCEPTION); }
	TH_MATH_ERROR is a macro which throws exceptions or modifies errno (depending on which compiling options are defined)

Enumerations
enum class	theoretica::MathError : int {   theoretica::None = 0x00 , theoretica::DivByZero = 0x01 , theoretica::OutOfDomain = 0x02 , theoretica::OutOfRange = 0x04 ,   theoretica::ImpossibleOperation = 0x08 , theoretica::NoConvergence = 0x10 , theoretica::InvalidArgument = 0x20 }
