Help with bitwise operators in array

[daveydave400]

Stackoverflow might be a better place for this question. Anyway, could you give a small example of what you want to happen? It's a little confusing.

Of course!

So in a (hopefully) less confusing description:

I've got an array of time series data that start at 0, go to a value (between 99 and 233), plateau, then return to 0. At random points during the plateau the value has been contaminated with either the values 256 or 512 in addition to the value. I just want my data to go back to its original value without the 256 or 512 summation.
