Input float for each exterior
CS2 normalises float across a trade-up: each input’s float becomes a 0–1 position inside its own range, those are averaged, and the average is applied to Desert Eagle | Golden Koi’s range of 0.00–0.12. To land a given exterior, your ten inputs must average the normalised float below.
| Target exterior | Output float | Required avg. input float |
|---|---|---|
| Factory New | 0.0350 | 0.2917 |
| Minimal Wear | 0.0950 | 0.7917 |
| Field-Tested | — | not reachable |
| Well-Worn | — | not reachable |

“Not reachable” means Desert Eagle | Golden Koi’s own float range never enters that exterior band — no combination of inputs can produce it.
