Detailed Description

Type properties and explicit runtime limits for exact-or-approximate reals.

Precision-dependent queries require a finite Precision or an approximate exemplar. There is no type-wide epsilon or digit count. Unimplemented limits are intentionally absent, rather than inheriting the zero-valued defaults of an unspecialized std::numeric_limits.
