Hi all!
Does any one of you know a source (book, internet) that deals with the effect of number representations on the solving of (linear) systems of equations? Thanks for your input in advance.

I assume you have done some google searches. Doing this, I got some interesting results. I entered the following keywords into google: number representations linear systems
To be honest, I don't know much about number representations. My expertise is different.

Juergen, could you elaborate on what you mean by number representations. The first things that come into my mind are decimal or exponential. In solving linear equations, both matrix and vector operations come into play; first matrix inversion, then matrix vector multiplication. I am guessing your query has to do with overflow/underflow in the number storage locations. I don't remember seeing any books that cover those kind of issues. ▼

Hi John! Well, sort of that. I'm looking for a way of estimating the error of a GaussElimination say (exact algorithm), depending on the base and mantissawidth of the floating point numbers used or the like ...

Hi Juergen,
When I was at the university in the 80's, my course in Numerical
