Worked on the mrousavy/expo repository to address a critical issue affecting barometric pressure accuracy in Expo Go for iOS. Focused on mobile and iOS development using Objective-C, the developer resolved a rounding error by converting pressure units from kilopascals to hectopascals and implementing double-precision arithmetic. This technical approach aligned the barometer data handling with the sensors package, ensuring consistency across components. The fix improved the accuracy of barometric readings, which benefits applications relying on precise altitude and pressure data. Throughout the month, the work centered on bug resolution, demonstrating attention to detail and a methodical approach to data integrity.
