# Values

Futhark has various primitive types: eight different types of integers (8 to 64 bit, both signed and unsigned), single and double precision floats, and booleans. Here are some examples.

```
def an_integer : i32 = 2
def an_unsigned_byte : u8 = 2
def a_boolean = true
def a_double : f64 = 2.0
```

Numeric literals are overloaded, such that `2`

can be any numeric
type, and decimal literals like `2.0`

must be either `f32`

or
`f64`

.
