 h-cosine

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

    Cosine of the angle specified by angle-in-radians. The h-cosine
    argument is the address of an H-floating number that is this
    cosine. MTH$HCOS writes the address of the cosine into h-cosine.

 angle-in-radians

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

    Angle (in radians). The angle-in-radians argument is the address
    of a floating-point number. For MTH$HCOS, angle-in-radians
    specifies an H-floating number.
