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 MAC-10 | Malachite’s range of 0.00–0.50. 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 | 0.0700 |
| Minimal Wear | 0.1100 | 0.2200 |
| Field-Tested | 0.2650 | 0.5300 |
