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
