Built-in Operators
==================
{{#include ../links.md}}
The following operators are built-in, meaning that they are always available, even when using a [raw `Engine`].
All built-in operators are binary, and are supported for both operands of the same type.
| Operators | Assignment operators | Supported types<br/>(see [standard types]) |
| ------------------------- | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `+`, | `+=` | <ul><li>`INT`</li><li>`FLOAT` (if not [`no_float`])</li><li>[`Decimal`][rust_decimal] (requires [`decimal`])</li><li>`char`</li><li>[string]</li></ul> |
| `-`, `*`, `/`, `%`, `**`, | `-=`, `*=`, `/=`, `%=`, `**=` | <ul><li>`INT`</li><li>`FLOAT` (if not [`no_float`])</li><li>[`Decimal`][rust_decimal] (requires [`decimal`])</li></ul> |
| `<<`, `>>` | `<<=`, `>>=` | <ul><li>`INT`</li></ul> |
| `&`, <code>\|</code>, `^` | `&=`, <code>\|=</code>, `^=` | <ul><li>`INT` (bit-wise)</li><li>`bool` (non-short-circuiting)</li></ul> |
| `&&`, <code>\|\|</code> | | <ul><li>`bool` (short-circuits)</li></ul> |
| `==`, `!=` | | <ul><li>`INT`</li><li>`FLOAT` (if not [`no_float`])</li><li>[`Decimal`][rust_decimal] (requires [`decimal`])</li><li>`bool`</li><li>`char`</li><li>[string]</li><li>[BLOB]</li><li>numeric [range]</li><li>`()`</li></ul> |
| `>`, `>=`, `<`, `<=` | | <ul><li>`INT`</li><li>`FLOAT` (if not [`no_float`])</li><li>[`Decimal`][rust_decimal] (requires [`decimal`])</li><li>`char`</li><li>[string]</li><li>`()`</li></ul> |
```admonish tip.small
`FLOAT` and [`Decimal`][rust_decimal] also inter-operate with `INT`, while [strings] inter-operate
with [characters][string] for certain operators (e.g. `+`).
