Hexadecimals and you.
Elementary my dear Watson.
Hex numbers 0F
0 1 2 3 4 5 6 7 8 9
A B C D E F
10 11 12...
Decimal numbers 09
0 1 2 3 4 5 6 7 8 9
10 11 12 13 14 15
16 17 18...
Additionally hex goes A0FF as well.
Hex
A0=160 (16 x 10 = 160)
Decimal
160=160
Every tens place in hex equals sixteen.
Hex
10=16
16=22
1A=26
20=32 (decimals 16+16=32)
Decimal
10=10
16=16
20=20
22=22
26=26
32=32
Bits are in the same byte of an address.
8bits=1byte with ten placements.
The bits are as follows.
bit0? 0=0 neutral
bit1 1=1
bit2 2=2
bit3 4=4
bit4 8=8
bit5 10=16
bit6 20=32
bit7 40=64
bit8 80=128
bit9? FF=255 maximum (256th number including zero)
It can use any and every mixture of bits.
Example:bits 6,5,and 3 20+10+4=34 (52 in decimal).
007F in hex are the positive numbers.
80FF in hex are the negative numbers.
Couning down from FF.
Examples:
FF= 1
FE= 2
80= 127 (maximum negative)
7F= +127 (maximum positive)
To think,I learned hex all on my own,not in school.
