Decode date and time in a sequence of binary data
Ten bits have more states than three decimal digits So, the use of any other small number than 2 does not provide an advantage. Moreover, Boolean algebra provides a convenient mathematical structure for collection of bits, with a semantic of a collection of propositional variables. Boolean algebra operations are known as " bitwise operations " in computer science.
Boolean functions are also well-studied theoretically and easily implementable, either with computer programs or by so-named logic gates in digital electronics. This contributes to the use of bits to represent different data, even those originally not binary.
In statistics , binary data is a statistical data type described by binary variables , which can take only two possible values. Binary data represents the outcomes of Bernoulli trials —statistical experiments with only two possible outcomes. It is a type of categorical data , which more generally represents experiments with a fixed number of possible outcomes. The two values in a binary variable, despite being coded numerically as 0 and 1, are generally considered to exist on a nominal scale , meaning they represent qualitatively different values that cannot be compared numerically.
In this respect, also, binary data is similar to categorical data but distinct from count data or other types of numeric data. Often, binary data is used to represent one of two conceptually opposed values, e.
However, it can also be used for data that is assumed to have only two possible values, even if they are not conceptually opposed or conceptually represent all possible values in the space. For example, binary data is often used to represent the party choices of voters in elections in the United States , i. In this case, there is no inherent reason why only two political parties should exist, and indeed, other parties do exist in the U.
The input is an invalid XML string, or the wrong encoding has been specified. The specified encoding is invalid or not supported. If the default encoding is chosen, conversion will be cheap, as strings and binaries are both internally represented as byte arrays.
The input cannot be represented in the specified encoding. Only the first 8 bits of the supplied integers will be considered. Conversion of byte sequences is particularly cheap, as items of binary type are internally represented as byte arrays. The conversion is very cheap and takes no additional memory, as items of binary type are internally represented as byte arrays. The first base elements of the sequence '0',..
