The relation of the approximate value table bits is as follows.

D2-D0	tilt
0	±∞
1	1
2	1
3	0
4	0
5	−1
6	−1
7	−∞

Refer to the following two tables to find D6-D3 of the approximate value table.

D6-D3	tilt (D2-D0 = 1or7)	Tilt (D2-D0 = 3or5)
0	prohibited	prohibited
1	1.5	1 / 1.5
2	2	1/2
3	3	1/3
4	4	1/4
5	6	1/6
6	8	1/8
7	12	1/12
8	16	1/16
9	24	1/24
A	32	1/32
B	48	1/48
C	64	1/64
D	96	1/96
E	128	1/128
F	prohibited	prohibited

Approximate values ​​are only ± ∞, 1, 0 and the values ​​in the above table. From this, find the closest absolute value to the actual slope, and set D0-2 and D6-3 as approximate values.
