+exactly the same value when compiled with Intel's C++ compiler and using `_Quad` as the underlying type: this is a current limitation of
+our code. Round tripping when using `__float128` as the underlying type is possible (both for GCC and Intel).
* Conversion from a string results in a `std::runtime_error` being thrown if the string can not be interpreted
as a valid floating point number.
* Division by zero results in an infinity being produced.
* Type `float128` can be used as a literal type (constexpr support).
+* When using the Intel compiler, the underlying type defaults to `__float128` if it's available and `_Quad` if not. You can override
+the default by defining either `BOOST_MP_USE_FLOAT128` or `BOOST_MP_USE_QUAD`.
+* When the underlying type is Intel's `_Quad` type, the code must be compiled with the compiler option `-Qoption,cpp,--extended_float_type`.
