The (>>) operator is use to shift the bits of an expression to the right, maintaining sign.
Syntax
result = expression1 >> expression2
The >> operator syntax has these parts:
Part |
Description |
result |
Any variable. |
expression1 |
Any expression. |
expression2 |
Any expression. |
Example
The >> operator shifts the bits of expression1 right by the number of bits specified in expression2. The sign bit of expression1 is used to fill the digits from the left. Digits shifted off the right are discarded. For example, after the following code is evaluated, temp has a value of -4: 14 (11110010 in binary) shifted right two bits equals -4 (11111100 in binary).
temp = -14 >> 2;
document.write(temp);

 To run the code above, paste it into JavaScript Editor, and click the Execute button.
