entPhySensorPrecision 1.3.6.1.2.1.99.1.1.1.3

The number of decimal places of precision in fixed-point sensor values returned by the associated entPhySensorValue object. This object SHOULD be set to '0' when the associated entPhySensorType value is not a fixed-point type: e.g., 'percentRH(9)', 'rpm(10)', 'cmm(11)', or 'truthvalue(12)'. This object SHOULD be set by the agent during entry creation, and the value SHOULD NOT change during operation.
