#C reads a following object, which must be a list of length two whose elements are both reals. These reals denote, respectively, the real and imaginary parts of a complex number.
If the two parts as notated are not of the same data type, then they are converted according to the rules of floating-point contagion described in section Contagion in Numeric Operations.
#C(real imag) is equivalent to #.(complex (quote real) (quote imag)), except that #C is not affected by *read-eval*. See the function complex.
Figure 2--21 contains examples of the use of #C.
#C(3.0s1 2.0s-1) ;A complex with small float parts. #C(5 -3) ;A "Gaussian integer" #C(5/3 7.0) ;Will be converted internally to #C(1.66666 7.0) #C(0 1) ;The imaginary unit; that is, i.
