 complex-conjugate

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

    The complex conjugate (r,-i) of the complex number specified by
    complex-number. MTH$DCONJG and MTH$GCONJG write the address of
    this complex conjugate into complex-conjugate. For MTH$DCONJG,
    the complex-conjugate argument specifies the address of a D-
    floating complex number. For MTH$GCONJG, the complex-conjugate
    argument specifies the address of a G-floating complex number.

 complex-number

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

    A complex number (r,i), where r and i are floating-point numbers.
    The complex-number argument is the address of this floating-
    point complex number. For MTH$DCONJG, complex-number specifies
    a D-floating number. For MTH$GCONJG, complex-number specifies a
    G-floating number.
