Ejecuta este código
#include <iostream> int main() { std::cout << "min() = " << std::numeric_limits<float>::min() << '\n' << "min_exponent10 = " << std::numeric_limits<float>::min_exponent10 << '\n' << std::hexfloat << "min() = " << std::numeric_limits<float>::min() << '\n' << "min_exponent = " << std::numeric_limits<float>::min_exponent << '\n'; }
Salida:
