I was told that (i >> 3) is faster than (i开发者_Go百科/8) but I can\'t find any information on what >> is.Can anyone point me to a link that explains it?
I\'m writing ARM assembly code that at some point has to set a single bit of a register to 1. This is best done of course via \"register-or-bitmask\" method. However, according to ARM documentation, t
I am looking at big code base in C++. There i开发者_JS百科s line mentioned as below int capacity( ) const
Say I want to increment a number by a bitwise shift, i.e. 1, 2, 4, 8, 16, etc Is there a way to condense the i = i << 1 below to something like increment operator (++)?
bitwise operators only work on integers in PHP and the maximum size of an integer is 2^63 on 64bit servers. If I create a value greater than that it will cast my variable to a float and bitwise operat
I have fed the following code through a static analysis tool: u1 = (u1 ^ u2); // OK u1 = (u1 ^ u2) & u3;// NOT OK
Say I have four 32-bit numbers, defined so that their bits don\'t overlap, i.e. unsigned long int num0 = 0xFF000000;
Can you guys please explain the below program int main() { int max = ~0; printf(\"%d\\n\",max); return 0;
My function takes in a 32 bit int and I need to return a 0 or 1 if that number has a 1 in any even position. I cant use any conditional statements I also can only access 8 bits at a time.
In a shift left operation for example, 5 << 1 = 10 10 << 1 = 20 then a mathematical equation can be made,
