问题描述
我正在使用python代码，其中一个方程式的平方根为负。我使用 cmath.sqrt 来解决它。我从该方程式获得的所有答案均以虚/复数形式显示（例如x.xxxxx j ）。我不想得到那个虚/复数，因为我随后使用的代码无法读取那些虚/复数。因此，如何避免不得到虚数？或以其他方式，如何将这些虚数转换为实数？或如何删除那些 j。谢谢。
I am using a python code, where one of the equations got sqrt root of negative value. I use cmath.sqrt to solve it. All answers I got from that equation are shown in imaginary/complex number (e.g. x.xxxxxj). I don't want to get that imaginary/complex number as the code that I use subsequently cannot read those imaginary/ complex number. As such, how can I avoid not to get imaginary numbers? OR in other way, how can I convert those imaginary number into real ones? or how can I remove those "j". Thanks.
推荐答案
如果我理解您的问题，您要么想要
If I understand your question you either want
abs(z)
或
z.real
