Generate a value given a floating point number, using formatting defined within this class.
The formatting mainly applies if formatting as a string. For example, was is
the number base? should a sign always be included? are leading zeros requried?
The formatting could include properties related to other types. For example, generate
an error if attempting to convert a negative floating point number to an unsigned integer.
