In addition, notes such as this one specify non-essential information that provides additional background or rationale. |
Finally, you can mentally add the following to any code fragments in this document:
// Include all of Ratio files #include <boost/ratio.hpp> using namespace boost;
Boost.Ratio aims to implement the compile time ratio facility in C++0x, as proposed in N2661 - A Foundation to Sleep On. That document provides background and motivation for key design decisions and is the source of a good deal of information in this documentation.
The Boost.Ratio library provides:
ratio
, for specifying compile
time rational constants such as 1/3 of a nanosecond or the number of
inches per meter. ratio
represents a compile time
ratio of compile time constants with support for compile time arithmetic
with overflow and division by zero protection.
boost::ratio<N, D>
in the form of a std::basic_string
which can be useful for I/O.
ratio
<> in the context
of Boost.MPL numeric metafunctions.
