What does the [x/2] notation mean, here?

  It's floor(_) - as in, floor(1.999) = 0, but floor(2.001) = 2. If you look carefully the upper flange of the [] square brackets is missing, which makes it a floor. https://en.wikipedia.org/wiki/Floor_and_ceiling_functions https://en.wikipedia.org/wiki/Floor_and_ceiling_functions

    > floor(1.999) = 0 it's 1 not 0

  It's the floor function https://en.wikipedia.org/wiki/Floor_and_ceiling_functions https://en.wikipedia.org/wiki/Floor_and_ceiling_functions (Had to check the TeX code to figure that out, MathJax let you do that with a right click on the equation.)
