Enables the use of uppercase characters in floating-point and hexadecimal integer output. Has no effect on input.
1) enables the uppercase flag in the stream str as if by calling str.setf(std::ios_base::uppercase).
2) disables the uppercase flag in the stream str as if by calling str.unsetf(std::ios_base::uppercase).
This is an I/O manipulator, it may be called with an expression such as out << std::uppercase for any out of type std::basic_ostream or with an expression such as in >> std::uppercase for any in of type std::basic_istream.
Parameters
| str | - | reference to I/O stream |
Return value
str (reference to the stream after manipulation).
Example
1 2 3 4 5 6 7 8 9 | #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';} |
Output:
1 2 3 4 | 0x2a with uppercase: 0X2A0x2a with nouppercase: 0x2a1e-10 with uppercase: 1E-101e-10 with nouppercase: 1e-10 |
