Significance arithmetic

Significance arithmetic typically refers to the way numerical values are represented and manipulated in contexts where precision and accuracy are crucial, such as in scientific calculations. It relates to the concept of significant figures (or significant digits), which represent the precision of a measurement. Key principles of significance arithmetic include: 1. **Significant Figures**: The digits in a number that carry meaning contributing to its precision. This includes all non-zero digits, any zeros between significant digits, and trailing zeros in a decimal number.
