CMPLX(3f)

DESCRIPTION
CMPLX(X [, Y [, KIND]]) returns a 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
Fortran 77 and later

CLASS
Elemental function

SYNTAX
RESULT = CMPLX(X [, Y [, KIND]])

ARGUMENTS

X The type may be INTEGER, REAL, or COMPLEX. Y (Optional; only allowed if X is not COMPLEX.) May be INTEGER or REAL. KIND (Optional) An INTEGER initialization expression indicating the kind parameter of the result.

RETURN VALUE
The return value is of COMPLEX type, with a kind equal to KIND if it is specified. If KIND is not specified, the result is of the default COMPLEX kind, regardless of the kinds of X and Y.

EXAMPLE
          program test_cmplx
              integer :: i = 42
              real :: x = 3.14
              complex :: z
              z = cmplx(i, x)
              print *, z, cmplx(x)
          end program test_cmplx
