8.53 COMPLEX — Complex conversion function

Description:
COMPLEX(X, Y) returns a complex number where X is converted to the real component and Y is converted to the imaginary component.
Standard:
GNU extension
Class:
Elemental function
Syntax:
RESULT = COMPLEX(X, Y)
Arguments:
X The type may be INTEGER or REAL.
Y The type may be INTEGER or REAL.
Return value:
If X and Y are both of INTEGER type, then the return value is of default COMPLEX type.

If X and Y are of REAL type, or one is of REAL type and one is of INTEGER type, then the return value is of COMPLEX type with a kind equal to that of the REAL argument with the highest precision.

Example:
program test_complex
    integer :: i = 42
    real :: x = 3.14
    print *, complex(i, x)
end program test_complex
