Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled

A large number whose value differs between naming systems, equal to one million million, ten to the twelfth power, in the short scale used in English-speaking countries and much of the world, and to one million million million, ten to the eighteenth power, in the long scale used in many European languages, where ten to the twelfth is a billion; the trillion is used for national economies, debts and data volumes, and its ambiguity between scales is a source of error.

Why it exists Filled

Let an agent explain the trillion and its short and long scale values, support converting and expressing large numbers, describe its uses in economics and computing, and prevent scale confusion.

Distinguishing features Filled

  • Scale-dependent
  • Economic use
  • SI prefix tera
  • Ambiguity

What robots and AI may and may not do Derived, awaiting review

May

  • explain scale values
  • support conversion
  • describe uses
  • prevent confusion

Note: Affordances listed as what may be done; prohibitions collected from the text.

  • Which entry fits number naming?
  • How can this number be converted between scales, prefixes and scientific notation?
  • Which entry fits scientific notation?
