VMS Help RTL Routines, MTH$, MTH$xIMAG  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Imaginary Part of a Complex Number routine returns the
    imaginary part of a complex number.

    Format

      MTH$AIMAG  complex-number

      MTH$DIMAG  complex-number

      MTH$GIMAG  complex-number

      Each of the above formats corresponds to one of the floating-
      point complex types.

1 - Returns

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_floating
    access:       write only
    mechanism:    by value

    Imaginary part of the input complex-number. MTH$AIMAG returns
    an F-floating number. MTH$DIMAG returns a D-floating number.
    MTH$GIMAG returns a G-floating number.

2 - Argument

 complex-number

    OpenVMS usage:complex_number
    type:         F_floating complex, D_floating complex, G_floating
                  complex
    access:       read only
    mechanism:    by reference

    The input complex number. The complex-number argument is the
    address of this floating-point complex number. For MTH$AIMAG,
    complex-number specifies an F-floating number. For MTH$DIMAG,
    complex-number specifies a D-floating number. For MTH$GIMAG,
    complex-number specifies a G-floating number.
