This is a lesson video for [High School Information I] 2-1-8: Errors. We explain rounding errors, data loss errors, digit loss errors, and truncation errors in a three-part series: their nature, causes, and solutions. 🎉 [Tokyo Shoseki "New Edition Information I" p. 67; Jikkyo Publishing "Latest News I" p. 81; Suken Publishing "Information I" p. 95; Nihon Bunkyo Publishing "Information I" p. 127] 📌 [Apology] Regarding an Example of Data Loss Errors In the example of data loss errors in the video (starting at 4:20), the second value in the long division is actually [0.00000011111 × 2^1], which is missing one zero. Please reinterpret the original formula as (1.0101 x 2^1) + (1.1111 x 2^-5). I apologize for the incorrect information.
