Numbers

Numbers can be represented many different ways.
The ALU processes them as 2's complement signed ints.

Base	Representation	Example	Equals (Binary/Decimal)
Binary	b followed by 8 bits	b00000011	00000011/3
Octal	@ followed by 3 octal digits	@037	00011111/-1
Hexadecimal	0x followed by 2 hexi digits	0xFA	11111010/-6
Decimal	decimal number with +/- (any length)	-2	11111110/-2
Wildcard	*, for when value doesn't matter	*	UNDEFINED

Note: the * wildcard number is technically undefined in value, but this specific assembler will always resolve it to 0. However, this behaviour should not be depended on, and simply writing 0 will also produce a 0 with only one character.

Examples

IN	BINARY OUT	DECIMAL OUT
0xFF	11111111	-1
0x1F	00011111	31
@131	01011001	89
+8	00001000	8
+1	00000001	1
+0	00000000	0
0	00000000	0
-0	00000000	0
-1	11111111	-1
-6	11111010	-6
-128	10000000	-128
+126	01111110	126
