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

    The Hyperbolic Cosine routine returns the hyperbolic cosine of
    the input value.

    Format

      MTH$COSH  floating-point-input-value

      MTH$DCOSH  floating-point-input-value

      MTH$GCOSH  floating-point-input-value

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

1 - Returns

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_floating
    access:       write only
    mechanism:    by value

    The hyperbolic cosine of the input value  floating-point-input-
    value. MTH$COSH returns an F-floating number. MTH$DCOSH returns a
    D-floating number. MTH$GCOSH returns a G-floating number.

2 - Argument

 floating-point-input-value

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_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$COSH, floating-point-input-
    value specifies an F-floating number. For MTH$DCOSH, floating-
    point-input-value specifies a D-floating number. For MTH$GCOSH,
    floating-point-input-value specifies a G-floating number.
