Y (optional)

must be of type integer or real. It must not be present if X is of type complex.

KIND (optional)

must be a scalar integer initialization expression.

Class

Elemental function

Result Type and Attributes

• It is of type complex.
• If KIND is present, the kind type parameter is that specified by KIND; otherwise, the kind type parameter is that of the default real type.

Result Value

• If Y is absent and X is not complex, it is as if Y were present with the value zero.
• If Y is absent and X is complex, it is as if Y were present with the value AIMAG(X).
• CMPLX(X, Y, KIND) has the complex value whose real part is REAL(X, KIND) and whose imaginary part is REAL(Y, KIND).

Examples

CMPLX (-3) has the value (-3.0, 0.0).
