@ -17,6 +17,14 @@ Hexadecimal: `$D323`, `0x2a2`
When using Intel syntax for inline assembly, another hexadecimal syntax is available: `0D323H`, `2a2h`.
It is not allowed in any other places.
The type of a literal is the smallest type of undefined signedness
that can fit either the unsigned or signed representation of the value:
`200` is a `byte`, `4000` is a `word`, `75000` is an `int24` etc.
However, padding the literal to the left with zeroes changes the type
to the smallest type that can fit the smallest number with the same number of digits and without padding.
For example, `0002` is of type `word`, as 1000 does not fit in one byte.
## String literals
String literals can be used as either array initializers or expressions of type `pointer`.
