What is the purpose of a unary “+” before a call to std::numeric_limitsmembers?
I saw this example in cppreference's documentation for std::numeric_limits #include <limits> #include <iostream> int main() { std::cout << "type\tlowest()\tmin()\t\tmax()\n\n"; std::cout << "uchar\t" << +std::numeric_limits<unsigned char>::lowest() << '\t' << '\t' << +std::numeric_limits<unsigned char>::min() << '\t' << '\t' << +std::numeric_limits<unsigned char>::max() << '\n'; std::cout << "int\t" << std::numeric_limits<int>::lowest() << '\t' << std::numeric_limits<int>::min() << '\t' << std::numeric_limits<int>::max() << '\n'; std::cout << "float\t" << std::numeric_limits<float>::lowest() << '\t' << std::numeric_limits<float>::min() << '\t' << st...
