Can you be more specific? I can't imagine needing to cut a longer piece into a known number of smaller pieces, rather than smaller pieces of a known size. Even if you do, won't the nice numbers be lost by having to account for kerf width? I've also built a deck and choosing the quantity of material to buy probably involved some dividing to see how many pieces I can get from a big one. But I would add a rough estimate for kerf width and length error. Dividing metric materials is often easy because they're sized in easily divisible numbers like 2.4, 3.6, or 4.8 m.
