This update fixes calculation problems and makes entry easier. • Adding and subtracting feet-and-inch lengths now gives the right answer (12' 6" + 8' 3" = 20' 9") • Multiply or divide by any number, including decimals (10' × 2 = 20') • Results can be negative, and dividing by zero shows a clear message • Results follow your Precision setting and show ≈ when rounded • New decimal key and a layout that fits smaller iPhones, landscape and iPad • Sharing, restoring from history and the fraction picker work reliably • Clearer wording in many languages
