| What's really left unexplained here is where the need came about
| for precision to be represented in this way. Like -- at first the
| article made it seem like they were using (presumably IEEE)
| floating-point decimals, and then merely _serializing_ them as
| strings. But floating-point decimals don 't include precision;
| the precision _can 't_ vary from one to another in the way
| described here.
|
| This means that the decimal strings described here are _not_
| merely serializations of the decimal floats, rather they 're
| _prior_ to the decimal floats. That leaves the question, then, of
| where they 're coming from. So where, then?
