    type:         H_floating
    access:       write only
    mechanism:    by reference

    Sine of the angle specified by angle-in-degrees. MTH$HSIND writes
    into h-sine the address of an H-floating number that is this
    sine.

 angle-in-degrees

    OpenVMS usage:floating_point
    type:         H_floating
    access:       read only
    mechanism:    by reference

    Angle (in degrees). The angle-in-degrees argument is the address
    of an H-floating number that is this angle.
