reverse

For example i have an operation in C like this:

((unsigned int)ptr & 0xff000000))

The result is bf000000. What do i need at this moment is how to reverse the above i.e. determine the ptr by using the result from the operation and offcourse 0xff000000 . I am asking if there's any simple way to implement this in C, tnx.

Hi, Can you please explain the below lines, with some good examples. A left arithmetic shift by n is equivalent to multiplying by 2n (provided the value does not overflow), while a right arithmetic shift by n of a two's complement value is equivalent to dividing by 2n(2… >>> More

I've been given the task of porting Java's Java.util.Random() to JavaScript, and I've run across a huge performance hit/inaccuracy using bitwise operators in Javascript on sufficiently large numbers.

For the life of me, I can't remember how to set, delete, toggle or test a bit in a bitfield. Either I'm unsure or I mix them up because I rarely need these. So a "bit-cheat-sheet" would be nice to have. For example: flags = flags | FlagsEnum.Bit4; // Set bit 4. or if ((flags == FlagsEnum.Bit4))… >>> More
