1. Arithmetic left shift logic left
The arithmetic left shift and the logical left shift are the right 0:
Like 00101011.
Shift arithmetic left one: 01010110
Shift logic left one: 01010110
For binary values, the left-shift n-bit equals the
1. Left shift operatorThe left shift operator 1) Its general format is as follows:Value NUM Specifies the number of bits to shift the value to move.Left-shift rule remembers only one point: Discard the highest bit, 0 the minimum bitIf the number of

There are too many cows in the garden, and there are almost some typesArticleSome people may have written things that the scalpers have written. Even if they don't, it seems that they don't have that skill.
Today, I wrote a very interesting
Arithmetic left shift operator>> operation rules:according to the binary form to move all the numbers to the right of the towering digits, low-shifted out (discard), high position of the vacancy complement the sign, that is, positive 0, negative
The shift operator is also for the binary "bit", which mainly includes the left shift operator (>>), and the signed right shift operator (>>).
1. Left shift operatorThe left-shift operator, represented by "public class Data17{public static void
The difference between right-shift operator >> and unsigned right-shift operator >>> in JavaIn making a PCM audio encountered this character, but I see some of the Baidu's interpretation of the place can not make me very understand, so I
Let's say move left, move left to shift all bits of a number to the left, and in C with the int i = 1;i = i In other words, 1 of the 2 binary is 000 ... 0001 (here 1 the number of front 0 is related to the number of int, 32-bit machine, GCC has 31 0)
Both the left and right shifts are the concepts of bit operations. We know that computers store data based on binary, so the concept of left and right shifts is important. This article deals with a 32-bit machine. [left] discard highest bit, 0
The types and functions of left-shift and right-hand commands:left shift instruction: the left shift command moves the bit bits of the operand to the left n bits, and the vacated bits are filled with 0.The left-shift directive contains SAL and SHL,
