-We are now seeing a widespread use of mobile computing devices with touch screens, where the display size is typically much smaller than paper pages and traditional computer monitors; it seems that there is much to be gained by breaking free of the restricted precision of traditional document formats.

-The remainder of this document will be organised as follows: In Chapter \ref{Proposal} we give an overview of the current state of the research in document formats, and the motivation for implementing ``infinite precision'' in a document format. We will outline our approach to research in collaboration with David Gow\cite{}. In Chapter \ref{Background} we provide more detailed background examining the literature related to rendering, interpreting, and creating document formats, as well as possible techniques for increased and possibly infinite precision. In Chapter \ref{Progress} gives the current state of our research and the progress towards the goals outlined in Chapter \ref{Introduction}.
+We have implemented a proof of concept document viewer compatable with a subset of the SVG standard, which has allowed us to explore the limitations of floating point arithmetic and possible approaches to achieving arbitrary precision document formats. Using the Rational representation of the GNU Multiple Precision (GMP) library\cite{granlund2014GMP} we are able to implement correct rendering of SVG test images seperated by arbitrary distances. We demonstrate the trade off between performance cost and the accuracy of rendering
