SensorPrecision ::= TEXTUAL-CONVENTION
    STATUS       current
    DESCRIPTION
        "When in the range 1 to 9, SensorPrecision is the number 
        of decimal places in the fractional part of 
        a SensorValue fixed-point number.  When in the range -8 to
        -1, SensorPrecision is the number of accurate digits in 
        a SensorValue fixed-point number.

        SensorPrecision is 0 for non-fixed-point numbers.

        Agent implementors must choose a value for SensorPrecision 
        so that the precision and accuracy of a SensorValue is 
        correctly indicated.

        For example, a temperature sensor that can measure 0o to 
        100o C in 0.1o increments, +/- 0.05o, would have a 
        SensorPrecision of 1, a SensorDataScale of units(0), and a 
        SensorValue ranging from 0 to 1000.  
        The SensorValue would be interpreted as (degrees C * 10).

        If that temperature sensor's precision were 0.1o but its 
        accuracy were only +/- 0.5o, then the SensorPrecision would 
        be 0. The SensorValue would be interpreted as degrees C.

        Another example: a fan rotation speed sensor that measures RPM 
        from 0 to 10,000 in 100 RPM increments, with an accuracy of 
        +50/-37 RPM, would have a SensorPrecision of -2, a 
        SensorDataScale of units(9), and a SensorValue ranging from 0 
        to 10000. The 10s and 1s digits of SensorValue would always 
        be 0.

    SYNTAX INTEGER (-8..9)

SensorValue ::= TEXTUAL-CONVENTION
    STATUS       current
    DESCRIPTION
        "For sensors that measure voltsAC, voltsDC, 
        amperes, watts, hertz, celsius, cmm
        this item is a fixed point number ranging from 
        -999,999,999 to +999,999,999.  Use the value 
        -1000000000 to indicate underflow. Use the value 
        +1000000000 to indicate overflow.  Use SensorPrecision
        to indicate how many fractional digits the SensorValue
        has.


        For sensors that measure percentRH, this item
        is a number ranging from 0 to 100.

        For sensors that measure rpm, this item
        can take only nonnegative values, 0..999999999.

        For sensors of type truthvalue, this item 
        can take only two values: true(1), false(2).

        For sensors of type specialEnum, this item
        can take any value in the range (-1000000000..1000000000),
        but the meaning of each value is specific to the 
        sensor.

        For sensors of type other and unknown, 
        this item can take any value in the range 
        (-1000000000..1000000000), but the meaning of the values
