Namespaces
namespace	LatticeTester
	Lattice namespace.
namespace	LatticeTester::Random
	This class generates random numbers (in fact pseudo-random numbers).

Macros

Functions
std::int64_t	LatticeTester::Random::randInt (std::int64_t i, std::int64_t j)
	Return a random integer in \([i, j]\).
NTL::ZZ	LatticeTester::Random::randInt (NTL::ZZ i, NTL::ZZ j)
	This is an overload of the previous method to create an NTL::ZZ integer in the range \([i,j]\).
double	LatticeTester::Random::randU01 ()
	Returns a random number in \([0, 1)\).
std::uint64_t	LatticeTester::Random::randBits (int64_t s)
	Returns random blocks of \(s\) bits ( \(s\)-bit integers).
void	LatticeTester::Random::setSeed (uint64_t seed)
