In Boolean logic, the majority function (also called the median operator) is the Boolean function that evaluates to false when half or more arguments are false and true otherwise, i.e. the value of the function equals the value of the majority of the inputs. Representing true values as 1 and false values as 0, we may use the (real-valued) formula: The "−1/2" in the formula serves to break ties in favor of zeros when the number of arguments n is even. If the term "−1/2" is omitted, the formula can be used for a function that breaks ties in favor of ones.
