# Data Types

### The Boolean Type

As in most other programming languages, a Boolean type in *Silicon* has two possible values: `true` and `false`. Booleans are one bit in size. The Boolean type in *Silicon* is specified using `bool`.

### Integer Types

|  Length | Signed |
| :-----: | :----: |
|  8-bit  |  `i8`  |
|  16-bit |  `i16` |
|  32-bit |  `i32` |
|  64-bit |  `i64` |
| 128-bit | `i128` |

### Floating-Point Types

| Length |  Type |
| :----: | :---: |
| 16-bit | `f16` |
| 32-bit | `f32` |
| 64-bit | `f64` |
