Signature used by the Logic class, which parses languages such as tptp, smtlib, etc... Mainly used to parse first-order terms, it is also used to parse tptp's THF language, which uses higher order terms, so some first-order constructs such as conjunction, equality, etc... also need to be represented by standalone terms.

Simply an alias to the Logic signature.

Signature required by terms for typing first-order polymorphic terms.

Floating points are complicated so this documentation is not in anyway sufficient. A detailed description of the theory together with the rationale of several models decisions as well as a formal semantics of the theory can be found in
