在生物医学领域的各种研究中,对实验检测和计算所得的数据往往都要进行修约。过去习惯使用“四舍五入法”进行数的修约,该方法是不正确的,我们应将其废除。根据国家标准《出版物上数字用法的规定》,数的修约应遵照“四舍六入”的法则进行,下面作一介绍,请广大作者遵照执行。(1)数的修约规则的简明口诀:4舍6入5看后,5后有数便进1,5后为0看左数,左数奇进偶舍弃。(2)数的修约操作示例见表1。
In various studies in the field of biomedicine, the data obtained from the testing and calculation of experiments often have to be revised. In the past, it was incorrect to use the “rounding method” to revise a few numbers, and we should abolish it. According to the national standard “Digital Usage of Publications,” the number of amendments to the contract should be in accordance with the “rounding” rule, make an introduction below, the majority of authors to comply with the implementation. (1) the number of rounding rules concise formulas: 4 to 6 into 5 to see after a few after 5 into 1,5 after 0 to see the left number, the odd number into the left even give up. (2) The number of rounding operation example shown in Table 1.
