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:
min() = 1.17549e-38 min_exponent10 = -37 min() = 0x1p-126 min_exponent = -125
