This should be easy for C++ people though. But I was asked how to do it in C#.开发者_高级运维 Shouldnt be much of difference.
I have some performance-heavy code that performs bit manipulations. It can be reduced to the following well-defined problem:
I\'m using Math.ceil( Math.abs( x ) )inside a loop. Can anyone realize any optim开发者_开发百科ization for this operation? (Bitwise or what?)
I found some interesting bit twiddling in \"source\\common\\unicode\\utf.h\" file of ICU library (International Components for Unicode). The bit twiddling is intended for checking whether a number is
I need a way to tag a pointer as being either part of set x or part of set y (ie: the tag has only 2 \'states\'), I\'m that means one can assume untagged = x and tagged = y.

I\'m making use of BitSet in Java to store values I have to serialize and deserialize into/from lower abstraction levels. This is to create a file-format container.
I know what they do, I just don\'t understand when you\'d get a use for th开发者_如何学Cem..When you need to manipulate individual bits of a chunk of data (like a byte or an int). This happens frequen
x <<= y(x = x << y) x >>= y(x = x >> y) x >>>= y (x = x >>> y)
Please refer to the following code for radix sort: class RadixSort { public static void radix_sort_uint(int[] a, int bits)
