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 ...
Performs a Bitwise Right Shift operation on the binary values of two input rasters. 図OutRas = Raster("InRas1") >> 1 説明 ラスター入力で演算子を使用すると、結果はラスターになります。 ただし、すべての入力値が数字の場合、結果は数字になります。 式に複数の演算子が含まれている場...
Summary Performs a Bitwise Right Shift operation on the binary values of two input rasters. IllustrationOutRas = Raster("InRas1") >> 1 Discussion When using an operator with a raster input, the result will be a raster. However, if all inputs are numbers, the result is a number. When ...
In the above example, we have created a variable a with the value 3. Notice the statement var result = a << 2 Here, we are performing 2 bits left shift operation on a. Right Shift Operator The right shift operator shifts all bits towards the right by a certain number of specified bit...

>>> (Zero-fill right shift) This operator shifts the first operand the specified number of bits to the right. Excess bits shifted off to the right are discarded. Zero bits are shifted in from the left. The sign bit becomes 0, so the result is always non-negative. ...
For example, a byte contains 8 bits; applying this operator to a value whose bit pattern is "00000000" would change its pattern to "11111111". The signed left shift operator "<<" shifts a bit pattern to the left, and the signed right shift operator ">>" shifts a bit pattern to the...
