 h-sinh

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

    Hyperbolic sine of the input value specified by floating-point-
    input-value. The h-sinh argument is the address of an H-floating
    number that is this hyperbolic sine. MTH$HSINH writes the address
    of the hyperbolic sine into h-sinh.

 floating-point-input-value

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

    The input value. The floating-point-input-value argument is
    the address of a floating-point number that is this value. For
    MTH$HSINH, floating-point-input-value specifies an H-floating
    number.
