abstract struct Int
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 the lowest between Int32
, Int64
and UInt64
in which the number fits:
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
9223372036854775808 # UInt64
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
