About

Class library for C++ that manages integer overflows

check if adding two numbers will overflow$ g++ -I$(brew --prefix safeint)/include example.cpp -o example && ./example

prevent integer overflow in multiplication operations

$ #include <SafeInt.hpp>
int main() { SafeInt<int> a = 100000; SafeInt<int> b = 100000; auto result = a * b; }

validate user input won't cause integer wraparound

$ #include <SafeInt.hpp>
SafeInt<unsigned int> value = user_input; // throws on overflow

safely convert between different integer types

$ #include <SafeInt.hpp>
SafeInt<int> small = SafeInt<long long>(large_value);

compile C++ code using safe integer library headers$ g++ -I$(brew --prefix safeint)/include -std=c++11 myprogram.cpp -o myprogram
