Namespaces
namespace	gsl
	The gsl package creates an interface to the GNU Scientific Library for C++.
namespace	gsl::math
	Mathematical constants.

Functions
template<typename T >
bool	gsl::is_odd (T const &n)
	Check if odd: only really makes sense for integral types. More...
template<typename T >
bool	gsl::is_even (T const &n)
	Check if even: only really makes sense for integral types. More...
template<typename T >
short	gsl::sign (T const &x)
	Find the sign of x: returns +1 for a value of zero to be consistent with GNU Scientific Library. More...
int	gsl::is_real (double const x)
	Variation on gsl_finite: returns 1 for a real number, 0 for infinite or NaN. More...
