I would like to do some physics problems in high precision. I cannot find any examples or sample worksheets that are accessable on a basic level. I just want real numbers ( including large and small in scientific notation ) I am pretty sure this is not too hard, perhaps it is too simple to be explained? Any help would be appreciated.
Your question is a little vague. We do have arbitrary (fixed) precision real and complex numbers.
sage: R = RealField(1000)
sage: a = R(5.0000001^5.0000001)
sage: a

By messing around I got my calcs to work, and are consistent with the above. I just find this, and even more the published material a bit abstract, and I was looking for just a bit more. I may publish a worksheet for others in the future which will illustrate these basic features.
That would be great! It's possible there is stuff out there, but I just wasn't sure what you were looking for.

Perhaps it would help if you described one specific problem that you are working on.
