    floor(-2024pi)=-floor(2024pi)-1
    I=int[-2024pi,ceil(-2024pi)](floor(x))dx (everything else cancels)
    width=ceil(-2024pi)+2024pi
    height=floor(-2024pi)
    I=floor(-2024pi)•(ceil(-2024pi)+2024pi)
    I=({2024pi}-1)•floor(-2024pi)

    Here is the link to that previous video where I looked at the case with integer bounds and bounds going to infinity:

    I(a, b) = Int[a, b] floor(x)
    I(a, b) = Sum[a, b-1] x
    I(-c, c) = Sum[-c, c-1]
    -c + 1 through c - 1 cancel each other out, leaving -c
    I(-c, c) = -c
    In this case I(-2024pi, 2024pi) = -2024pi

    I kept getting myself confused with the bounds until I drew a number line and marked various points, setting floor(2024 pi) = N. Then it was easy enough to calculate the three contributions.

      Hi adandap. Yep kind of some basic book keeping here. Kind of cool how everything cancels! Not sure I’ll remember this as a formula however that you always get the lower bound as the answer.
