Section 8,9,2: COMPLEX

 Real and complex numbers are floating-point representations.

 COMPLEX (COMPLEX*8) data is eight contiguous bytes aligned on an
 arbitrary byte boundary.  The low-order four bytes contain REAL
 (REAL*4) data that represents the real part of the complex number.
 The high-order four bytes contain REAL data that represents the
 imaginary part of the complex number.  For information on the
 ranges of REAL data, see REAL (within the Data Constants section of
 Help).

 DOUBLE COMPLEX (COMPLEX*16) data is 16 contiguous bytes aligned on
 an arbitrary byte boundary.  The low-order bytes contain DOUBLE
 PRECISION (REAL*8) data that represents the real part of the
 complex number.  The high-order eight bytes contain DOUBLE
 PRECISION data that represents the imaginary part of the complex
 data.  For information on the ranges of DOUBLE PRECISION data, see
 DOUBLE_PRECISION (within the Data Constants section of Help).
