1. 19 A unary operator is named by using the key word operator followed by the unary operator symbol.

2. Collate is a postfix unary operator

3. Bitwise Complement (~) – This operator is a unary operator, denoted by ‘~’

4. Assume that the Boolean formula is given using arbitrary unary and binary Boolean operators

5. Other articles where Bivariant system is discussed: phase: Unary systems: …is stable) the system is divariant—i.e., two degrees of freedom exist

6. In mathematics and abstract algebra, a relation algebra is a residuated Boolean algebra expanded with an involution called converse, a unary operation.

7. In set theory, a common convention is that the language has 2 constants, 0 and 1, and two binary functions · and +, and one unary function −.

8. The following operators perform Bitwise or shift operations with operands of the integral numeric types or the char type: Unary ~ (Bitwise complement) operator Binary << (left shift) and >> (right shift) shift operators Binary & (logical AND), (logical OR), and ^ (logical exclusive OR) operators

9. If a constructor does not take any data arguments, it is nullary. -- nullary type constructor with two nullary data constructors data Bool = False | True -- non-nullary type constructor with one non-nullary data constructor data Point a = Point a a -- non-nullary type constructor with... data Maybe a = Nothing -- ...nullary data constructor | Just a -- ...unary data constructor
