DCMPLX — Double complex conversion function#

DCMPLX(X, Y)#

DCMPLX(X [,Y]) returns a double complex number where X is converted to the real component. If Y is present it is converted to the imaginary component. If Y is not present then the imaginary component is set to 0.0. If X is complex then Y must not be present.

Parameters

  • X – The type may be INTEGER, REAL, or COMPLEX.

  • Y – (Optional if X is not COMPLEX.) May be INTEGER or REAL.

Returns

The return value is of type COMPLEX(8)

Standard:

GNU extension

Class:

Elemental function

Syntax:
RESULT = DCMPLX(X [, Y])
Example:
program test_dcmplx
    integer :: i = 42
    real :: x = 3.14
    complex :: z
    z = cmplx(i, x)
    print *, dcmplx(i)
    print *, dcmplx(x)
    print *, dcmplx(z)
    print *, dcmplx(x,i)
end program test_dcmplx
