[英]Python float formatting: fixed total number of digits
I am saving some data with numpy.savetxt(path,array,fmt="%.2f %.2f %.2f %.2f %.2f")
and I want the text file to be formated nicely. 我用
numpy.savetxt(path,array,fmt="%.2f %.2f %.2f %.2f %.2f")
保存了一些数据,我想要很好地格式化文本文件。 I would like to limit the floats to a certain amount of digits, like this: 我想将浮点数限制为一定数量的数字,如下所示:
11.2345 -> 11.2
1.2345 -> 1.23
Currently I get: 目前我得到:
11.2345 -> 11.23
1.2345 -> 1.23
This destroys the layout of the text file. 这会破坏文本文件的布局。
