std::uppercase,std::nouppercase - std::uppercase,std::nouppercase

Synopsis¶

Defined in header <ios>
std::ios_base& uppercase( std::ios_base& str ); (1)
std::ios_base& nouppercase( std::ios_base& str ); (2)

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¶

// Run this code

#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:¶

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