python – 熊猫数据精度

参见英文答案 > How to round values only for display in pandas while retaining original ones in the dataframe?                                    1个
默认情况下,数据框中的数值仅存储6位小数.我如何获得完整的精度.

eg 34.98774564765 is stored as 34.987746. I do want the full value. 
eg2 0.00000565  is stored as 0. .
apart from applying formats to each data frame is there any global setting that helps preserving the precision.

谢谢

解决方法:

不,34.98774564765默认只打印六位小数：

>>> pandas.DataFrame([34.98774564765])
           0
0  34.987746

数据本身具有更高的精度：

>>> pandas.DataFrame([34.98774564765])[0].data[0]
34.98774564765

您可以通过更改pandas.options.display.precision来更改用于打印帧的默认值.

例如：

>>> pandas.set_option("display.precision", 8)
>>> pandas.DataFrame([34.98774564765])
                0
0  34.98774564765
