====== 16-Bit Absolute Value Comparison ======
===== Skate & Eins Method =====
N1 = 16-bit signed number at zeropage

N2 = 16-bit signed number at zeropage

Here we compare;

 |N1| and |N2|

in other representation

abs(N1) and abs(N2)

So, if N1 = 2000, N2 = -3000, N2 should be bigger since we compare the distance from zero.

Please note that equality is neglected here. Equal absolute values may end up in any of the two conditions.

<code asm>
	lda N1+1
	eor N2+1
	bmi differentSigns

// sameSigns:
	lda N1
	cmp N2
	lda N1+1
	sbc N2+1
	eor N1+1
	bmi num1IsBigger
	jmp num2IsBigger

differentSigns:
	clc
	lda N1
	adc N2
	lda N1+1
	adc N2+1
	eor N1+1
	bmi num1IsBigger

num2IsBigger:
	// ...add your code here for |N1| < |N2|...
	jmp endOfAbsCompare

num1IsBigger:
	//...add your code here for |N1| > |N2|...

endOfAbsCompare:
