1.1本规程旨在协助使用统一方法，指示报告岩土试验结果时被视为重要的位数，并四舍五入用于中间计算。 1.2本规程使用了传统舍入方法的变体（见规程E 29），该方法识别大多数手持式计算器通用的算法。

1.1 This practice is intended to assist in the use of uniform methods of indicating the number of digits that are to be considered significant and rounding for intermediate calculations when reporting geotechnical test results. 1.2 This practice uses a variation of the traditional rounding method (see Practice E 29) that recognizes the algorithm common to most hand-held calculators.
