Print real roots only in numpy

Question

I have something like this:

coefs = [28, -36, 50, -22]
print(numpy.roots(coefs))

Of course the result is:

[ 0.35770550+1.117926         


        

Answer 1

I hope this help.

 roots = np.roots(coeff);
 for i in range(len(roots)):
     if np.isreal(roots[i]):
         print(np.real(roots[i]))
