P.S.: Are you sure that your Test code is doing what you wanted it to do? It looks to me like there should be something like *rand++ in it...

The above testing code is a subset of my real code, where x is a value I just introduced to have a return value to show. It does not represent anything, and shouldn't be taken into account. The rand variable is a pointer to an array of random bools. I wanted to use it to create some randomness, but I didn't really succeed there. Very Happy

I solely wanted to point out the runtime of the different implementations. Smile

As Bits optimization, I also figured that there is no Reserve(int) function to pre-allocate the internal buffer. I think it would be a good idea to add such, because it sharply reduces the number of reallocates necessary. I also think that setting a bitmask can be vectorized. However, that would be a task for myself, because U++ is made to be portable. Smile

Thanks,
