In mathematics, a Boolean function is a function whose arguments and result assume values from a two-element set (usually {true, false}, {0,1} or {-1,1}). [ 1 ] [ 2 ] Alternative names are switching function , used especially in older computer science literature, [ 3 ] [ 4 ] and truth function (or logical function) , used in logic .
The heads of departments are members of the Cabinet of the United States, an executive organ that normally acts as an advisory body to the president. In the Opinion Clause (Article II, section 2, clause 1) of the U.S. Constitution , heads of executive departments are referred to as "principal Officer in each of the executive Departments".
In mathematics and theoretical computer science, analysis of Boolean functions is the study of real-valued functions on {,} or {,} (such functions are sometimes known as pseudo-Boolean functions) from a spectral perspective. [1] The functions studied are often, but not always, Boolean-valued, making them Boolean functions.
In mathematics and mathematical logic, Boolean algebra is a branch of algebra.It differs from elementary algebra in two ways. First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers.
The federal government of the United States (U.S. federal government or U.S. government) [a] is the common government of the United States, a federal republic located primarily in North America, comprising 50 states, five major self-governing territories, several island possessions, and the federal district (national capital) of Washington, D.C ...
The BIT data type, which can only store integers 0 and 1 apart from NULL, is commonly used as a workaround to store Boolean values, but workarounds need to be used such as UPDATE t SET flag = IIF (col IS NOT NULL, 1, 0) WHERE flag = 0 to convert between the integer and Boolean expression.
A Boolean function can be represented as a rooted, directed, acyclic graph, which consists of several (decision) nodes and two terminal nodes. The two terminal nodes are labeled 0 (FALSE) and 1 (TRUE). Each (decision) node is labeled by a Boolean variable and has two child nodes called low child and high child.
