[edit] Example

#include   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'; }

Output:

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