Hello all,

I am new to the Python language and writing a Runge-Kutta-Fellberg 7(8)
integrator in Python, which requires an extreme numerical precision for my
particular application. Unfortunately, I can not seem to attain it.
The interesting part is if I take my exact code and translate it to Matlab
code (so I use the exact same process and numbers), I get a far superior
precision (the one I am expecting, in fact). This leads me to think I need
to call a certain command in my Python script in order to make sure no
truncation errors are building up over my integration.

Has anyone had similar problems? Is there a difference between how Matlab
and Python store numbers, and if so how do I make Python more accurate?

I know there is a lot of packages out there, but this in fact overwhelmed me
a little bit and seems to prevent me from finding the answer to my question,
so I'm hoping someone with more experience will be able to enlighten me!

Best regards,

Jon
