**METACALL** maintains most of the types of the languages but not all are supported. If new types are added they have to be implemented in the [`reflect`](/source/reflect) module and also in the [`loaders`](/source/loaders) and [`serials`](/source/serials) to fully support it.

| Type | Value |
| :-----: | ------------------------------------------------------------------ |
| Boolean | `true` or `false` |
| Char | `-128` to `127` |
| Short | `-32,768` to `32,767` |
| Int | `-2,147,483,648` to `2,147,483,647` |
| Long | `–9,223,372,036,854,775,808` to `9,223,372,036,854,775,807` |
| Float | `1.2E-38` to `3.4E+38` |
| Double | `2.3E-308` to `1.7E+308` |
| String | NULL terminated list of characters |
| Buffer | Blob of memory representing a binary data |
| Array | Arrangement of values of any type |
| Map | List of elements formed by a key (String) value (Any) pair (Array) |

- Boolean is mostly represented by an integer value. There are languages that does not support it so it gets converted to a integer value in the memory layout.
