Crystal reports Crystal Reports中的默认排序算法是什么

我们有一个数据表，将数据推送到Crystal reports。我们注意到排序似乎不一致，并假设是四舍五入、四舍五入到偶数、奇数或类似的情况。它似乎没有遵循这种模式。这不是一套完整的数据，但以下是四舍五入工作原理的示例。有人知道这种模式是什么吗？我们需要能够对其进行可靠的测试。我应该注意到X总是四舍五入到Z，所以它是一致的

谢谢

通过右键单击字段并使用格式选项，可以明确指定所需的舍入。谢谢。我正试图确定目前使用的算法是什么。我越是看它似乎是随机的数字；好像克里斯托选择了一组数字进行取整，以便更接近实际的分组总数。你试过我的建议了吗？
