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
