Exemple

#include <iostream>
int main()
{
    std::cout << std::hex << std::showbase
              << "0x2a with uppercase: " << std::uppercase << 0x2a << '\n'
              << "0x2a with nouppercase: " << std::nouppercase << 0x2a << '\n'
              << "1e-10 with uppercase: " << std::uppercase << 1e-10 << '\n'
              << "1e-10 with nouppercase: " << std::nouppercase << 1e-10 << '\n';
}

Résultat :

0x2a with uppercase: 0X2A
0x2a with nouppercase: 0x2a
1e-10 with uppercase: 1E-10
1e-10 with nouppercase: 1e-10
