Functions
template<typename N >
bool	smash::almost_equal (const N x, const N y)
	Checks two numbers for relative approximate equality. More...
template<typename N >
bool	smash::almost_equal_physics (const N x, const N y)
	Same as smash::almost_equal, but for physical checks like energy-momentum conservation small_number is enough precision-wise. More...
template<typename T = std::initializer_list<double>>
bool	smash::is_any_nan (const T &collection)
	This function iterates through the elements of a collection and checks if any of them is NaN using the std::isnan function. More...
