Can anyone tell me an efficient approach to perform the divisio开发者_JAVA百科n operation without using \'/\'. I can calculate the integer value in log(n) steps using a method similar to binary search
I would like to learn what is bit interleaving. I have an example: a: 011 b: 101 --- c: 100111 As far as I see the bits of the number \"a\" are on pair positi开发者_运维技巧ons in the result and th
I\'m implementing Charikar\'s fast search on a locality sensitive hash and I\'m looking for a fast method of permuting bits (the kind of thing that can be done in one operation in MMIX) in C#.
Say I\'m given n=32. I want to know what log_2(n) is. In th开发者_开发问答is case, log_2(32) = 5.
Can somebody explain to me why the following code: var a = 0xFFFFFFFF; a &= 0xFFFFFFFF; a += 1; alert( \"a = \" + a );
Is there any way you can get any integer\'s lower-order n bits (where n can be any number betwe开发者_高级运维en 1 and 32) without previously pre-computing 32 bitmasks, one for each order, and using t
The ARM7-command set offers efficient ways to right rotate 32-bit values by an arbitrary amount in assembler. For the 2nd operand of an operation it is even \"for free\" by specifying ror #n as shifte
Why does this xor operation zero out? mysql> select 17246357237183571361 xor 13175113390712773921; +-----------------------------------------------+
Is it possible to determine the byte, or bytes, that have changed from a CRC16 calculation? For example, say I get a config file that is 780 bytes that includes the CRC16 as a two byte value at the e
What is the best way to reverse the significant bits of an integer in python and then get the resulting integer out of it?
