    What's the problem? You seem to have the right equation on hand.

    o yea sorry, the further question was;

    what would I use for m to achieve the minimum index? 1?

    As well, would I use the [+.5] or not, meaning destructive vs constructive.

    Those 2 were my detailed questions.

    M would have to be the smallest possible integer without the right-hand-side being less than or equal to 0.
