列CumulativeAdjustmentFactor的值为1.00000。
当我加载并打印它时，我得到了
1.0
如何保留相同的值？

答案 0 :(得分：0)
由于您的CumulativeAdjustmentFactor列类型为double，show方法只需调用toString的{{1}}，因此无法完成。
double > 1.0000.toString
1.0
的固有行为。
您可以转换为double类型以显示完整值。
答案 1 :(得分：0)
如果您想将其转换为字符串，那么我们已经通过示例讨论了here的format_number方法。这个方法需要一个数字来获得你想要的精度，并且会在pyspark实现中保留尾随零，scala spark我还没有测试过它。
