C++ 128/256-bit fixed size integer types

by

The Boost library has data types as part of multiprecision library, for types ranging from 128 to 1024 bits.

#include <boost/multiprecision/cpp_int.hpp>

using namespace boost::multiprecision;

int128_t mySignedInt128 = -1;
uint128_t myUnsignedInt128 = 2;
int256_t mySignedInt256 = -3;
uint256_t myUnsignedInt256 = 4;
int512_t mySignedInt512 = -5;
uint512_t myUnsignedInt512 = 6;
int1024_t mySignedInt1024 = -7;
uint1024_t myUnsignedInt1024 = 8;
