#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
