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

    The Complex Number Made from D- or G-Floating Point routines
    return a complex number from two D- or G-floating input values.

    Format

      MTH$DCMPLX  complx ,real-part ,imaginary-part

      MTH$GCMPLX  complx ,real-part ,imaginary-part

      Each of the above formats accepts one of floating-point complex
      types as input.

1 - Returns

    None.

2 - Arguments

 complx

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

    The floating-point complex value of a complex number. The complex
    exponential functions that have D-floating complex and G-floating
    complex input values write the address of this floating-point
    complex value into complx. For MTH$DCMPLX, complx specifies a
    D-floating complex number. For MTH$GCMPLX, complx specifies a
    G-floating complex number. For MTH$CMPLX, complx is not used.

 real-part

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

    Real part of a complex number. The real-part argument is the
    address of a floating-point number that contains this real part,
    r, of (r,i). For MTH$DCMPLX, real-part specifies a D-floating
    number. For MTH$GCMPLX, real-part specifies a G-floating number.

 imaginary-part

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

    Imaginary part of a complex number. The imaginary-part argument
    is the address of a floating-point number that contains this
    imaginary part, i, of (r,i). For MTH$DCMPLX, imaginary-part
    specifies a D-floating number. For MTH$GCMPLX, imaginary-part
    specifies a G-floating number.
