# != — inequality

[Syntax and values](README.md)

## Behavior and details

`!=` asks whether two values differ. It gives the opposite Boolean answer to [`==`](equal.md), including when comparing lists, maps, or `none`.

Pliro does not automatically turn text into numbers for this comparison: `2 != "2"` is true. Automatically changing a value's type is called **coercion**; this operator does not do it. If a function reports “nothing found” using empty text `""`, compare with that empty text. `none` is a different value.

## Example

```pliro
# language: en
say 1 != "1"
say none != false
say([1] != [2])
```
