AIMAG — Imaginary part of complex number¶

AIMAG(Z)¶

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.

Parameters: Z – The type of the argument shall be COMPLEX.
Returns: The return value is of type REAL with the kind type parameter of the argument.

Standard:: Fortran 77 and later, has overloads that are GNU extensions
Class:: Elemental function

Syntax:

RESULT = AIMAG(Z)

Example:

program test_aimag
  complex(4) z4
  complex(8) z8
  z4 = cmplx(1.e0_4, 0.e0_4)
  z8 = cmplx(0.e0_8, 1.e0_8)
  print *, aimag(z4), dimag(z8)
end program test_aimag
