Complex logical expressions can be defined using the logical and (&&), logical or (||) and logical not (!). These operators can be applied to NumericTypes that are considered Boolean results. That is, true for a non-zero value, and false otherwise. The returned NumericType is true if both operands are true for the and operator, at least one is true for the or operator, and the operand is false for the not operator. In all other cases, a false is returned. To make sure Logical expressions are readable, the and and or operators are defined to have the same priority. Use parentheses to disambiguate a logical expression and to make it more readable.
