This is a type purely made to be appended to objects of type AString. Various constructors accept integer and floating point values, along with formatting options. The specialization of functor AppendableTraits will use a given (or defaulted) instance of class NumberFormat to format the encapsulated value and append the result to the AString in question.

Details on Formats:
Details on the options of formatting integer and floating point numbers are documented with class NumberFormat.

| union { ... } alib::strings::TDec< TChar >::v |
The data.
The union to hold an integral or floating point value provided with the different constructors.
