I have a query which looks like: select count(*) from m1 WHERE(m1.`resource` & 1472 ); Although I have index on resource it doesn\'t use it. How can this be opti开发者_如何学编程mized to use on
I\'ve implemented the code here in C# to get the MSB of an int. I\'m not certain what I need to do with the log reference table and the main code to exten开发者_开发问答d the code to 64 bit.
Guys i want to understand , how the widening or narrow implicit casting is internally implemented in java.I know that it involves bit fiddling.
Does anyone know of an algorithm similar to De Bruijn\'s LSB, but for MSB? Or alternately the most efficient way of determining the MSB?
1 Byte = 8 bits. I have to work on 120 bits. So 15 Byte. This 120 bits will be in the form of 00010101000000............
What I must do is open a file in binary mode that contains stored data that is intended to be interpreted as integers.I have seen other examples such as Stackoverflow-Reading “integer” size bytes fr
I\'m working on an assignment and I can\'t figure out how to implement this. I have to make a function sadd(int x, int y) that returns the numbers added together unless it overflows (then just return
How can I implement division using bit-wise opera开发者_StackOverflowtors (not just division by powers of 2)?
I\'m currently having a problem with bitshift operators. I\'m not familiar with it so pardon the lame question.
I have a 2 collections of bitmasks, 1 has permissions that I want to combine, and the other collection has bitmasks I want to remove.
