#### 16.4.1.4 Unary Operators ¶

The unary operators take a single operand of any dimensions and operate on each of its elements independently. The unary operators are:

`-`

  Inverts the sign of each element.

`+`

  No change.

`NOT`

  Logical inversion: each positive value becomes 0 and each zero or negative value becomes 1.

Examples:

`-{1, -2; 3, -4}` | ⇒ | `{-1, 2; -3, 4}`
`+{1, -2; 3, -4}` | ⇒ | `{1, -2; 3, -4}`
`NOT {1, 0; -1, 1}` | ⇒ | `{0, 1; 1, 0}`
