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 22.214.171.124 (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 126.96.36.199 (Sharpsign B), Section 188.8.131.52 (Sharpsign O), Section 184.108.40.206 (Sharpsign X), and Section 220.127.116.11 (Sharpsign R).
