ETYM Cf. French précision, Latin praecisio a cutting off. Related to Precise.
The quality or state of being precise; exact limitation; exactness; accuracy; strict conformity to a rule or a standard; definiteness.
Precision is reproducibility. SayingThese measurements are precis is the same as saying,The same measurement was repeated several times, and the measurements were all very close to one anothe. Don’t confuse precision with accuracy.
1. The extent of detail used in expressing a number. For example, 3.14159265 gives more precision—more detail—about the value of pi than does 3.14. Precision is related to, but different from, accuracy. Precision indicates degree of detail; accuracy indicates correctness. The number 2.83845 is also more precise than 3.14, but it is less accurate for pi. Compare accuracy.
2. In programming, numeric values are often referred to as single-precision or double-precision values. The difference between the two is in the amount of storage space allotted to the value. See also double-precision, single-precision.
Tačnost broja, u smislu broja decimalnih mesta koja se uzimaju u obzir. Na primer, 3.17259324876 ima veću preciznost od 3.17. Preciznost je oblast koja budi opsesivne tendencije kod ljudi; srećom, računari imaju više smisla za kontrolu.
