Intel® Fortran Compiler 18.0 Developer Guide and Reference
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 COMPLEX*8; COMPLEX(8) is specified as COMPLEX*16; 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.
