Bitwise Shift Operators

Posted on by ignatiusdavidmarkal

Write to Your Note Don’t learn it then forget it.

Bitwise Shift Operators

This operators are often forgotten, but by using this operator will save memory and is more secure, especially on   game programming and encryption techniques.

Bitwise Shift Right operator “>>”
64 >> 1, then 64 is converted into a binary number 1000000 then shifted 1 bit to the right to be 100000, so 64 >> 1 = 32. To facilitate recall x >> n then any shift to the right then x will be divided by 2 n
64 >> 1 = 32, because 64: 2 = 32
64 >> 2 = 16, because 64: 2: 2 = 16
64 >> 3 = 8, because 64: 2: 2: 2 = 8
63 >> 1 this would mean 63: 2 = 31, the result is an integer

Bitwise Shift Left operator “<<“
To the left is the opposite of the slide slide right
8 ‘<<‘ 1 then 8 is converted into a binary number to 1000. Then do the shift by 1 bit to the left. So that original 1000 will be 10000 (at the time of shifting the rightmost value is filled with bits 0)
8 ‘<<‘ 1 = 16 for 8 x 2 = 16
8 ‘<<‘ 2 = 32 for 8 x 2 x 2 = 32
8 ‘<<‘ 3 = 64 for 8 x 2 x 2 x 2 = 64

Bitwise Shift Operators Zero Fill “>>>”
Leftmost bit (high-order bit) is used to determine the sign (sign) of a number (whether positive or negative). Bit value of 0 indicates a positive value and a bit value of 1 indicates a negative value. Example: Continue reading →

“WRITE ONCE IN BLOG READ ANYWHERE BY INTERNET” 😛 😛 😀

JUST TO LEARN HOW TO MAKE A SIMPLE GAME IN HTML5 JS AND JQUERY

NewBieOnly!

.

Html 5 tag that you must know it :
<!DOCTYPE html>
<html>
<head>
<title>SimpleGridGame</title>
</head>
<body>
<canvas id=”yourcanvasId” width=”480″ height=”640″></canvas>
</body>
</html>
Example of Javascript implementation:
– build 2d array in js for Grid Map
For example we make array with size : 30x10var map1 = [
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
