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 Section (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 Section (Sharpsign B), Section (Sharpsign O), Section (Sharpsign X), and Section (Sharpsign R).

This section summarizes the full syntax for numbers. Syntax of a Rational Syntax of a Float Syntax of a Complex
