2.3.2 Constructing Numbers from Tokens

A real is constructed directly from a corresponding numeric token; see Figure~2–9.

A complex is notated as a #C (or #c) followed by a list of two reals; see Sharpsign C.

The reader macros #B, #O, #X, and #R may also be useful in controlling the input radix in which rationals are parsed; see Sharpsign B, Sharpsign O, Sharpsign X, and Sharpsign R.

This section summarizes the full syntax for numbers.
