There is some inconsistency with the Intel library functions i.e. how do we convert between a long double and a BID_UINT128?

Can stddecimal be used:

• in android/ios?
• in browser (emscripten, wasm)?

template <char... C>
constexpr decimal32 operator "" DF();
template <char... C>
constexpr decimal64 operator "" DD();
template <char... C>
constexpr decimal128 operator "" DL();
template <char... C>
constexpr decimal32 operator "" df();
template <char... C>
constexpr decimal64 operator "" dd();
template <char... C>
constexpr decimal128 operator "" dl();

The library functions receive a flags parameter that is used to communicate exceptions. Figure out the best way to expose this. Review the spec and see what the required behaviour is.

The spec describes this in detail, implement and add tests. It will have to live in it's own header as we obviously can't change

The intel library functions receive a parameter that controls rounding, check what it required and either add a mechanism to control this.

The existing tests are designed to exercise the templates and the basic usage of the Intel library.

This shouldn't be done until the exception handling has been implemented.

operator>> has not been implemented.
A very basic operator<< has been implemented for debugging purposes but it needs completing.
