integer

comment

A 32-bit twos-complement integer type.

Representations in Jass code:

Decimal: Any number positive or negative, without the fractional part: -1, 0, 1337
Octal: Any number beginning with 0: 07 == 7, 08 is a syntax error.
Hexadecimal: If the number starts with 0x or $ then the following comprises a hex value: 0x01da, $01da
Character: An ASCII charcater in single-quotes is interpreted as a byte value: 'd' is 100.
4 characters (aka rawcode, FourCC): Four ASCII characters in single-quotes are interpreted as a 32-bit integer: 'dddd' = (100 << 24) + (100 << 16) + (100 << 8 ) + 100 = 1677721600 + 6553600 + 25600 + 100 = 1684300900

note

Lua is also compiled with 32-bit integers (game's exe is 64-bit).

Octal: The Jass2Lua compiler does not support integers defined in octal representation and crashes. (Reforged, v1.32.10)
Charater: same as Jass
4 characters: 'hfoo' represents a human footman object code in Jass. These are also called "raw codes" or FourCC. In Jass, these are automatically read as integers by the Jass interpreter. If you use Lua, you must manually convert a string of four characters to integer with FourCC("hfoo"). This is true for ability IDs, unit/destructable types etc. in any place where the game's API needs an integer to refer to the type of an object.
