Detailed Description

Numerical stream adapter that can be assigned to any output stream and allows streaming of numerical values.

In contrast to the default std::ostream implementation, this class is able to handle nan and inf values correctly.

This class can be used like any other std::ostream, as shown in the following Example:

ofstream ofs("myfile.txt");
NumericalOstream os(ofs); // create numerical stream and attach it to the file stream

int a = 4;
os << a << std::endl;

os << 1.234f << std::numeric_limits<float>::quiet_NaN() << std::endl;

os << "This is a string" << std::endl;

uint32 x = 0x12345F;
os << std::hex << x; // write x in hexadecimal format

Constructor & Destructor Documentation

NumericalOstream()

NumericalOstream ( std::ostream &  s )

inline

Constructs a NumericalOstream around the specified existing std::ostream.

All outputs written to the NumericalOstream will be relayed to that std::ostream internally. The std::ostream must exist while this NumericalOstream object is existent.
