Builtin Types

Odin has a large number of builtin types compared to most other languages.

Signed Integers

• i8

• i16

• i32

• i64

• i128

Unsigned Integers

• u8

• u16

• u32

• u64

• u128

• uintptr. An unsigned integer guaranteed to be sizeof(rawptr)

byte exists as an alias of u8. It is not a distinct type.

Endian-specific types

By default, all numeric types have platform-native endianness. These types override that, which is primarily useful for things like parsing file formats, or reading data from the network. This specifically represents the byte-endianness. For that reason, u8 and i8 do not have endian-specific variants, as they are only 1 byte.

Big Endian:

• i16be

• u16be

• i32be

• u32be

• i64be

• u64be

• i128be

• u128be

• f16be

• f32be

• f64be

Little Endian:

• i16le

• u16le

• i32le

• u32le

• i64le

• u64le

• i128le

• u128le

• f16le

• f32le

• f64le
