Unary Operators

General Info: Unary Operator

An operation with only one operand (a single input). Common unary operators include + plus, - minus, and bitwise not. Some operators can function as both unary and binary operators. For example, + and - operators can serve as either.

Languages Focus

What unary operators are supported in additoin to the standard plus, minus, and bitwise not.

VB.Net:

An operation with only one operand (a single input). A unary operator method can return any type but takes only one parameter, which must be the type of the containing class. In addition to the obvious +, -, and Not operators, VB.Net also offers:

isFalse
isTrue

+ Indicates positive value (numbers are positive without this)
- Negates an expression
++ Increment operator by 1
-- Decrement operator by 1
! Logical complement operator (inverts the value of a boolean)
~ Bitwise inversion operator (works on integral data types)
