COMPLEX Statement

Statement: Specifies the COMPLEX data type.

COMPLEX

COMPLEX([KIND=] n)

COMPLEX*s

DOUBLE COMPLEX

n	Is kind 4, 8, or 16.
s	Is 8, 16, or 32. COMPLEX(4) is specified as COMPLEX8; COMPLEX(8) is specified as COMPLEX16; COMPLEX(16) is specified as COMPLEX*32.

If a kind parameter is specified, the complex constant has the kind specified. If no kind parameter is specified, the kind of both parts is default real, and the constant is of type default complex.

DOUBLE COMPLEX is COMPLEX(8). No kind parameter is permitted for data declared with type DOUBLE COMPLEX.

Example

COMPLEX ch
COMPLEX (KIND=4),PRIVATE :: zz, yy   !equivalent to COMPLEX*8 zz, yy
COMPLEX(8) ax, by        !equivalent to COMPLEX*16 ax, by
COMPLEX (kind(4)) y(10)
complex (kind=8)  x, z(10)
