I have 2 numbers in javascript that I want to bit and. They both are 33bit long in C#: ((4294967296 & 4294967296 )==0) is false
I have found one example in Data and Communication Networking book written by Behrouza Forouzan regarding upper- and lowercase letters which differ by only one bit in the 7 bit code.
I\'d like a shortcut for the following little function, where performance is very important (the function is called more than 10.000.000 times):
I found the following thread: Calculate broadcast address from ip and subnet mask and there the link to http://lpccomp.bc.ca/netm开发者_开发技巧ask/netmask.c
Mapping signed to unsigned integers bijectively can be done using common techniques like Two\'s complement. Unfortunately, they fail to map small negative integers to small numbers. For compression al
Thanks to some very helpful stackOverflow users at Bit twiddling: which bit is set?, I have constructed my function (posted at the end of the question).
certain compiler, derived from EDG gives me expression has no effect warning on this line return 1 << ((i == j) + (k == l) + ((i == k) & (j == l)));
I have a string encoded in Little Endian format (least-significant-byte first), and I want to decode开发者_运维问答 it into a Number. For the encoder, the first bit of the last byte reflects whether t
long make_checksum(const char* str) { long chk=0; long rot=0; while(*str) { rot<<=9; rot|=(rot>>23);
I am trying to take one\'s complement of 0 to get 1 but I get 4294967295. Here is开发者_开发知识库 what I have done:
