Typedefs
typedef __int128_t	impala::int128_t
	We use the c++ int128_t type. This is stored using 16 bytes and very performant. More...
typedef boost::multiprecision::number < boost::multiprecision::cpp_int_backend < 256, 256, boost::multiprecision::signed_magnitude, boost::multiprecision::unchecked, void > >	impala::int256_t
	Define 256 bit int type. More...

Functions
int256_t	impala::ConvertToInt256 (const int128_t &x)
int128_t	impala::ConvertToInt128 (int256_t x, int128_t max_value, bool *overflow)
int128_t	impala::abs (const int128_t &x)
uint64_t	impala::HighBits (int128_t x)
	Get the high and low bits of an int128_t. More...
uint64_t	impala::LowBits (int128_t x)
std::ostream &	impala::operator<< (std::ostream &os, const int128_t &val)
	Prints v in base 10. More...

#define BOOST_NOEXCEPT

We want to use boost's multi precision library which is only available starting in boost 1.5. For older version of boost we will use the copy in thirdparty. The boost library is for C++11 on a newer version of boost than we use. We need to make these #defines to compile for pre c++11
