     Type:  defect                   |      Status:  new        
 Priority:  normal                   |   Milestone:  Unscheduled
Component:  scipy.integrate          |     Version:  0.9.0      
 Keywords:  Odeint, scipy.integrate  |  
-------------------------------------+--------------------------------------
 First system info:
 Ubuntu 10.04
 Python 3.1.2
 Scipy 0.9.0
 Matplotlib 1.1.0(unofficial version ported through a sprint)

 In the code attached I've seperated the offending section. In the section
 shown variable alpha is set to 3*10^4 and the code works giving the
 expected responsed of an RLC circuit. However if I alternatively set alpha
 to 30000 the response returned by odeint is incorrect. Additionally if I
 set alpha to 3.2*10^4 the script won't even run. I also tried 3e4 and that
 doesnt give the proper results either.

 Thank you for your consideration.

 Best Regards,
 Jorge Garcia
