Precision
When used to describe floating-point numbers, precision refers to the number of bits used to hold the fractional part. The more precision a system uses, the more exactly it can represent fractional quantities.
Floating-point numbers are often classified as single precision or double precision. A double-precision number uses twice as many bits as a single-precision value, so it can represent fractional quantities much more exactly.

precision
"Precision is the measure of how close the data values are to each other for a number of measurements under the same analytical conditions. ICH has defined precision to contain three components: repeatability, intermediate precision, and reproducibility".

precision
1. The degree of mutual agreement among a series of individual measurements, values, or results; often, but not necessarily, expressed by the standard deviation. 2. With respect to a set of independent devices of the same design, the ability of these devices to produce the same value or result, given the same input conditions and operating in the same environment. 3. With respect to a single device, put into operation repeatedly without adjustments, the ability to produce the same value or result, given the same input conditions and operating in the same environment. Synonym (for defs. 1, 2, and 3) reproducibility. 4. In computer science, a measure of the ability to distinguish between nearly equal values. (188 ) 5. The degree of discrimination with which a quantity is stated; for example, a three-digit numeral to the base 10 discriminates among 1000 possibilities.

PRECISION
[L:143] A concept is made distinct, through analysis, "by making their characteristics successively clear". If all characteristic are thus made clear, the concept is made completely distinct; if it "does not contain too many characteristics" [i.e., to grasp at once?] it is precise. About analysis, Kant adds "since one cannot become certain by any proof whether all characteristics of a given concept have been exhausted by complete analysis, all analytic definitions must be held to be uncertain", suggesting that strictly speaking we can never know when a concept is completely distinct or precise.

Precision
The capacity of the system to discriminate between different values of input; the "fineness" with which different values for input can be inferred from measured values of output. The pooled deviation of observed from expected values of output, all divided by the amplification, yields the "index of precision". The square of the reciprocal of the index of precision is the measure of the amount of information that can be delivered by the system.
Specifically, precision is computed in several steps. First, the deviation of each observed value of output from the corresponding predicted value is squared; predicted values are determined from the curve relating input and output for all the data. The squared deviations are summed and divided by N-2, the number of "degrees of freedom"; the square root of the quotient is determined and is a number analogous to the standard deviation. This "root mean square deviation" is then divided by the slope of the input-output curve, i.e., the amplification, to yield the "index of precision"; it is assumed that the input-output relationship is linear.
See Accuracy.

Precision
Precision has the following meanings:
- In engineering, science, industry, and statistics, precision characterises the degree of mutual agreement among a series of individual measurements, values, or results — see accuracy and precision.
- In computing, precision means one of the following:
- the precision (number of digits) with which a value is expressed (e.g., the number of significant decimal digits or significant bits – a calculation which rounds to three digits is said to have a working precision or rounding precision of 3)
- the units of the least significant digit of a measurement; for example, if a measurement is 17.130 meters then its precision is millimeters (one unit in the last place, or ulp, is 1 mm)
- (in some programming languages and databases) the number of decimal places after the decimal point in a fixed-point number; to avoid confusion, this usage is best avoided.
- 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, precision is the percentage of documents returned that are relevant. This is often coupled with the recall measure. Together, the two scores are sometimes used to calculate the F1 Score.
- In music, Precision is the official march of the Royal Military College of Canada.
- In the game of contract bridge, Precision Club is a bidding system.
