Seemless is yet another big integer library for C++ with foucus on its seemless interface such that big integer class could be used as if it is just a primitive type.

The design focus is to provide a seemless way to use big integer with a close to zero learning curve.

• Default constructor
• Copy constructor
• Constructor by hexadecimal string
• Constructor by decimal string
• Constructor by binary string
• Automatic memory reallocation (by using STL)
• Explicit trim and downcast to unsigned long long
• Implicit cast to bool
• Addition: +, +=
• Subtraction: -, -=
• Muplication: *, *=
• Division: /, /=
• Mod: %, %=
• Exponential: pow()
• Comparision: ==, <, >, >=, <=
• Bitwise Operation: &, &=, |, |=, ^, ^=
• Bit shifting <<, <<=, >>, >>=
• Output to std::cout
• Input from std::cin
• Literal like 123456ULL that append after digit to create a big integer type (is this possible by macro?)
