NAME
aimag(3f) - [FORTRAN:INTRINSIC:NUMERIC:TYPE] Imaginary part of complex number

SYNTAX
result = AIMAG(Z)

DESCRIPTION
AIMAG(Z) yields the imaginary part of complex argument Z. The IMAG(Z) and IMAGPART(Z) intrinsic functions are provided for compatibility with G77, and their use in new code is strongly discouraged.

ARGUMENTS
Z The type of the argument shall be COMPLEX.

RETURN VALUE
The return value is of type REAL with the kind type parameter of the argument.

EXAMPLE
Sample program: 

    program demo_aimag
    use, intrinsic :: iso_fortran_env, only : real_kinds, &
    & real32, real64, real128
    implicit none
    complex(kind=real32) z4
    complex(kind=real64) z8
       z4 = cmplx(1.e0, 0.e0)
       z8 = cmplx(0.e0_real64, 1.e0_real64,kind=real64)
       print *, aimag(z4), aimag(z8)
    end program demo_aimag

STANDARD
[[FORTRAN 77]] and later
