Inexact real numbers are implemented as either single- or
double-precision @as-index{IEEE floating-point numbers}---the latter
by default, and the former only when support for 32-bit inexact
numbers is specifically enabled when the run-time system is built, and
only when a computation starts with numerical constants specified as
single-precision numbers. Inexact real numbers that are represented as
double-precision floating-point numbers are @deftech{flonums}.

The precision and size of exact numbers is limited only by available
memory (and the precision of operations that can produce irrational
