I have some old code like this: private int ParseByte(byte theByte) { byte[] bytes = new byte[1]; bytes[0] = theByte; BitArray bits = new BitArray(bytes); if (bits[0]) return 1; else return 0; } It's long and I figured I could trim it down like this: private int ParseBy...
If the value after the shift operator is greater than the number of bits in the left-hand operand, the result is undefined. If the left-hand operand is unsigned, the right shift is a logical shift so the upper bits will be filled with zeros. If the left-hand operand is signed, the right shift may or may not be a logica...
I want to know when I do 4<<2, what exactly happens underneath?? are there any multiplications performed or how is the value computed. if you have a reference to the implementation of shift operators please reply me. Thanks in advance ...
hi, I am doing code conversion from JavaScript to vb.net. I am stuck with the >>> operation. see the sample code and my attempt below: JavaScript: function test(a, b){ return (a << b) | (a >>> (32 - b)) } my attempt in vb.net: Private Function test(ByVal a As Integer, ByVal b As Integer) As Integer Return ((a << b) Or (...
I was looking at F# doc on bitwise ops: Bitwise right-shift operator. The result is the first operand with bits shifted right by the number of bits in the second operand. Bits shifted off the least significant position are not rotated into the most significant position. For unsigned types, the most significant bits are ...
Is the difference between integer multiply(temporarily forgetting about division) still in favor of shifting and if so how big is the difference? It simply seems such a low level optimization, even if you wanted it the shouldn't the (C#/Java) to bytecode compiler or the jit catch it in most cases? Note: I tested the compiled output for...
I read that Left shift e1< x=5; printf("%d",x<<3); Output is 40 but according to me it should be 30. and for x<<4 it is 80 .(but expected 40). Although for x<<1 and x<<2 outputs are 10 and 20 as expected.Please explain this logic. ...
