Overview
Int is the base type of all integer types.
There are four signed integer types: Int8
, Int16
, Int32
and Int64
,
being able to represent numbers of 8, 16, 32 and 64 bits respectively.
There are four unsigned integer types: UInt8
, UInt16
, UInt32
and UInt64
.
An integer literal is an optional #+
or #-
sign, followed by
a sequence of digits and underscores, optionally followed by a suffix.
If no suffix is present, the literal's type is Int32
, or Int64
if the
number doesn't fit into an Int32
:
1 # Int32
1_i8 # Int8
1_i16 # Int16
1_i32 # Int32
1_i64 # Int64
1_u8 # UInt8
1_u16 # UInt16
1_u32 # UInt32
1_u64 # UInt64
+10 # Int32
-20 # Int32
2147483648 # Int64
Literals without a suffix that are larger than Int64::MAX
represent a
UInt64
if the number fits, e.g. 9223372036854775808
and
0x80000000_00000000
. This behavior is deprecated and will become an error in
the future.
The underscore _
before the suffix is optional.
Underscores can be used to make some numbers more readable:
1_000_000 # better than 1000000
Binary numbers start with 0b
:
0b1101 # == 13
Octal numbers start with 0o
:
0o123 # == 83
Hexadecimal numbers start with 0x
:
0xFE012D # == 16646445
0xfe012d # == 16646445
See Integer
literals in the language reference.
