Thanks for kind reply. I am new to this python coding. Could you please
tell me how use bigfloat to fix this overflow problem
I am getting overflow for following values
v = numpy.linspace(0, 100, 10)
j= numpy.exp(v/1.3806488e-23)
I have tried to use In [30]: from bigfloat import *
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-30-45ecbac7174b> in <module>()
----> 1 from bigfloat import *
ImportError: No module named 'bigfloat'
