:int8

8-bit signed integer

:uint8

8-bit unsigned integer

:int16

16-bit signed integer

:uint16

16-bit unsigned integer

:int32

32-bit signed integer

:uint32

32-bit unsigned integer

:int64

64-bit signed integer

:uint64

64-bit unsigned integer

:intmax

largest type of signed integer available

:uintmax

largest type of unsigned integer available

:intptr

signed integer the same size as a pointer

:uintptr

unsigned integer the same size as a pointer
