    zyckser: I know you can use ldct but what's wrong with using dtec?

    I made a mistake, !-x is a decrementor and the formula should be -!x = x+1. (so !-x = x-1).

    Nice +1. mark2222's algorithm really is a fast 2's complement algorithm converted to an incrementor. 2's complement inverts the sign of a number and is equivalent to flipping all bits in a number and incrementing it. This means that if you flip all bits before you take the 2's complement you undo its bit flips and end up with just an incrementor (so !-x = x+1).
