11. Arithmetics

WLA is able to solve really complex calculations like

-((HELLO / 2) | 3)
skeletor_end-skeletor
10/2.5

so you can write something like

LD HL, data_end-data
LD A, (pointer + 1)
CP (TEST + %100) & %10101010

WLALINK also has this ability so it can compute the pending calculations WLA wasn’t able to solve.

The following operators are valid:

,	comma
|	or
&	and
^	power
<<	shift left
>>	shift right
+	plus
-	minux
#	modulo
~	xor
*	multiply
/	divide
<	get the low byte
>	get the high byte

Note that you can do NOT using XOR:

• VALUE_A ~ $FF is 8-bit NOT
• VALUE_B ~ $FFFF is 16-bit NOT

WLA computes internally with real numbers so (5/2)*2 produces 5, not 4.
