## FAQ

**How do I enter 10' 3 1/2"?**
Tap: 1 0 [ft] 3 [in] 1 [/] 2 - then any operator or =.

**Can I type decimal inches?**
Yes. 3.5 works and displays as 3 1/2".

**What does the ≈ badge mean?**
Your exact result does not land on the current fraction grid (e.g. 1/16), so the display is rounded to the nearest mark. The internal value stays exact. Tap the fraction button (1/8 → 1/16 → 1/32 → 1/64) to change display precision.

**Why did I get "범위 초과 / out of range"?**
The number is too large for exact fraction math. Real-world tape measurements are never affected.
