What\'s the best way to unstub the following functions? // Convert a bit-vector to an integer. int bitvec2int(boolean[] b)
How can I mult开发者_StackOverflow中文版iply and divide using only bit shifting and adding? To multiply in terms of adding and shifting you want to decompose one of the numbers by powers of two, like
Mycurrent开发者_如何学编程 project requires extensive use of bit fields. I found a simple, functional recipe for bit a field class but it was lacking a few features I needed, so I decided to extend it
I\'m dealing with a problem which needs to work with a lot of data. Currently its values are represented as an unsigned int. I know that real values do not exceed a limit of 1000.
I\'m converting some assembly code to C to be able to use it with the current compiler environment I have to work with.
If I have a 32 bit two\'s complement number and I want to know what is the easiest way to know of two numbers are equal... what would be the fastest bitwise operator to know this? I know xor\'ing both
In the yester Code Jam Qualification round http://code.google.com/codejam/contest/dashboard?c=433101#s=a&a=0 , there was a problem called Snapper Chain. From the contest analysis I came to know th
The problem is: given an integer val1 find the position of the highest bit set (Most Significant Bit) then, given a second integer val2 find a contiguous region of unset bits to the left of the positi
I have read through this SO question about 32-bits, but what about 64-bit numbers?Should开发者_开发百科 I just mask the upper and lower 4 bytes, perform the count on the 32-bits and then add them toge
