 h-cosh

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

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

 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 this input value. For MTH$HCOSH, floating-point-input-
    value specifies an H-floating number.
