Namespaces
namespace	NTL
	These functions are in the NTL namespace.

Functions
Conversion functions for compatibility with NTL.
These functions perform conversions between different types. Most of them do not really need explanations, but sometimes a specific logic is used when doing the conversion.
void	NTL::conv (std::int64_t &l, const char *c)
	Converts the array of characters (string) c into an std::int64_t l using the strtol() function of cstdlib.h.
void	NTL::conv (double &r, const char *c)
	Converts the array of characters (string) c into a double r using the strtod() function of cstdlib.h.
bool	NTL::IsZero (const std::int64_t &x)
	Returns the bool resulting of the statement x == 0.
void	NTL::clear (double &x)
	Sets x to 0.
void	NTL::clear (std::int64_t &x)
	Sets x to 0.
std::int64_t	NTL::IsOdd (const std::int64_t &x)
	Tests if x is odd.
void	NTL::set (std::int64_t &x)
	Sets x to 1.
Mathematical functions
These are complementary overloads to NTL power functions.
std::int64_t	NTL::power (std::int64_t p, std::int64_t i)
	Returns \(p^i\).
void	NTL::power2 (std::int64_t &z, std::int64_t i)
	Sets \(z = 2^i\).
void	NTL::power2 (NTL::ZZ &z, std::int64_t i)
	Sets \(z = 2^i\).
Inline functions for certain operators, again for compatibility with NTL.
static void	NTL::add (int64_t &x, const int64_t a, const int64_t b)
static void	NTL::sub (int64_t &x, const int64_t a, const int64_t b)
static void	NTL::SubPos (int64_t &x, const int64_t a, const int64_t b)
static void	NTL::negate (int64_t &x, const int64_t a)
static void	NTL::mul (int64_t &x, const int64_t a, const int64_t b)
static void	NTL::div (int64_t &x, const int64_t a, const int64_t b)
static void	NTL::rem (int64_t &x, const int64_t a, const int64_t b)
static void	NTL::sqr (int64_t &x, const int64_t a)
static void	NTL::MulAddTo (int64_t &x, const int64_t a, const int64_t b)
static void	NTL::MulSubFrom (int64_t &x, int64_t a, int64_t b)
static void	NTL::LeftShift (int64_t &x, const int64_t a, int64_t k)
static void	NTL::RightShift (int64_t &x, const int64_t a, int64_t k)

Detailed Description

This file offers a few basic utilities not available in NTL.

It is in the NTL namespace because it was initially seen (historically) as an expansion of NTL.
