**Announcement: We are hiring a PhD student to do research on functional high performance computing, including work on Futhark itself. See here for more details.**

# 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.

```
let an_integer : i32 = 2
let an_unsigned_byte : u8 = 2
let a_boolean = true
let 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`

.
