In computing, the precision (number of digits) with which a value is expressed (e.g., the number of decimal digits or bits).
With respect to a set of independent devices of the same design, precision is the ability of these devices to produce the same value or result, given the same input conditions and operating in the same environment. (As defined by Federal Standard 1037C and MIL-STD-188.)
With respect to a single device, put into operation repeatedly without adjustments, precision is the ability to produce the same value or result, given the same input conditions and operating in the same environment. (As defined by Federal Standard 1037C and MIL-STD-188.)
In information retrieval, a measure of the number of relevant documents in the set of all documents returned by a search. It forms a natural pair with recall.
