ANSI Common Lisp 2 Syntax 2.3 Interpretation of Tokens
2.3.2 Constructing Numbers from Tokens
A real is constructed directly from a corresponding numeric token;
see Figure 2.3.1 Numbers as Tokens.
A complex is notated as a #C (or #c) followed by a list
of two reals; see Section 220.127.116.11 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 18.104.22.168 Sharpsign B,
Section 22.214.171.124 Sharpsign O,
Section 126.96.36.199 Sharpsign X,
and Section 188.8.131.52 Sharpsign R.
