Ejecuta este código
#include <iostream> int main() { std::cout << "max() = " << std::numeric_limits<float>::max() << '\n' << "max_exponent10 = " << std::numeric_limits<float>::max_exponent10 << '\n' << std::hexfloat << "max() = " << std::numeric_limits<float>::max() << '\n' << "max_exponent = " << std::numeric_limits<float>::max_exponent << '\n'; }
Salida:
