What is the equivalent (in C#) of Java's >>> operator?
(Just to clarify, I'm not referring to the >> and << operators.)
506
The >>> operator is the unsigned right bit-shift operator in Java. It effectively divides the operand by 2 to the power of the right operand, or just 2 here.
>> is arithmetic shift right, >>> is logical shift right. In an arithmetic shift, the sign bit is extended to preserve the signedness of the number. For example: -2 represented in 8 bits would be 11111110 (because the most significant bit has negative weight).
The shift operator is a java operator that is used to shift bit patterns right or left.
The Java programming language also provides operators that perform bitwise and bit shift operations on integral types.
In C#, you can use unsigned integer types, and then the << and >> do what you expect. The MSDN documentation on shift operators gives you the details.
Since Java doesn't support unsigned integers (apart from char), this additional operator became necessary.

Java doesn't have an unsigned left shift (<<<), but either way, you can just cast to uint and shfit from there.
E.g.
(int)((uint)foo >> 2); // temporarily cast to uint, shift, then cast back to int If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
