8.75 DCMPLX — Double complex conversion function

Description:
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.
Standard:
GNU extension
Class:
Elemental function
Syntax:
RESULT = DCMPLX(X [, Y])
Arguments:

X The type may be INTEGER, REAL, or COMPLEX.
Y (Optional if X is not COMPLEX.) May be INTEGER or REAL.

Return value:
The return value is of type COMPLEX(8)
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
