Why the lower limit changes a search
A float filter expresses a request; it does not change a finish's supported values. Valve's finish documentation explains that finishes can use a restricted wear range. Consequently, a request below 0.05 will not necessarily suit every design. Check compatibility before concluding that an empty result means a missing item or a broken catalog. Keep the exact finish selected while investigating.
A hypothetical range example
Suppose a finish has a confirmed range of 0.10–0.70. This is a teaching example, not a claim about a named skin. A search from 0.00 to 0.07 has no overlap. A search from 0.08 to 0.12 leaves only 0.10–0.12. To find the cleanest available examples, start near the supported minimum rather than absolute zero. The upper limit similarly constrains heavily worn searches.
Set filters in a useful order
If your offer source provides a numerical float filter, select the exact weapon and finish first. Remove the exterior restriction and record the supported limits. Apply an appropriate float interval before adding an exterior condition. When results disappear, disable the last condition temporarily. The CASECS2 finder does not provide numerical float filtering: use it to choose designs, then review individual offer floats separately through available attributes and inspection.
Record technical limits separately from listings
| Check | Example record |
|---|---|
| Supported range | 0.10–0.70, hypothetical |
| Requested interval | 0.08–0.12 |
| Actual overlap | 0.10–0.12 |
| Other restrictions | Variant, exterior, availability |
Record the source of the limits. The lowest float among five visible listings is only a sample minimum, not proof of the technical minimum. Keep those values in separate columns. Use weapon and name search in the skin finder for design discovery; verify numerical limits separately at the individual-offer source.
Check overlap with a formula
For closed teaching intervals [a,b] and [c,d], lower bound L=max(a,c) and upper bound U=min(b,d). L>U means no intersection; L=U means one point with length 0. For [0.10,0.70] and [0.08,0.12], L=0.10, U=0.12 and length=0.02. These are hypothetical intervals, not a named finish specification. Check a provider filter’s endpoint rules separately. The overlap calculator checks the arithmetic in Russian.
