What does a skin's float value tell me?

The float is a decimal between 0.00 and 1.00 that dictates visual wear. The scale maps to five named conditions: Factory New (0.00-0.07), Minimal Wear (0.07-0.15), Field-Tested (0.15-0.38), Well-Worn (0.38-0.45), and Battle-Scarred (0.45-1.00). Skins closer to 0.00 look cleaner and typically carry higher price tags.
