Hello Sviatoslav
How is this different from <decimal/decimal> from the Decimal TR? It's
implemented in libstdc++.
See http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3407.html.

I'm not sure it should be in Qt. It might be more useful to make an
independent library that works with other compilers besides GCC until C++17
comes along.
