>Assembly How does the AND (&) operation work on 16 bit

Hi Ugly God

>>58972614
AND basically sets the bits common to both numbers and clears the rest.

eg

10110010
01011010
--------- AND
00010010

Some common uses, taking the lower 4 bits from a number:

10110110
00001111
--------- AND
00000110

Make a number even (rounding towards 0):

10110101
11111110
--------- AND
10110100

>What's Google?
It's a bit operator. Bitwise and.
11110000 & 10101010 = 10100000.
The numbers being 16bit doesn't change anything.

It ANDs each bit:
1001 & 1100 == 1000
Basic math that you could have googled.

ANDing with 0 is used to clear bits

ORing with 1 is used to set bits

XORing with 1 is used to flip bits

see I thought that but on a test review, he has:
>0x9057 & 0x2F2A
>Result = 0x0002

>>58972840

1001000001010111    (0x9057)
0010111100101010    (0x2f2a)
----------------- AND
0000000000000010    (0x0002)

Only the second bit is common to both numbers, so the answer is 2
