-The first half of this chapter will be devoted to documents themselves, including: the representation and displaying of graphics primitives\cite{computergraphics2}, and how collections of these primitives are represented in document formats, focusing on well known standards currently in use\cite{plrm, pdfref17, svg2011-1.1}.
-
-We will find that although there has been a great deal of research into the rendering, storing, editing, manipulation, and extension of document formats, these widely used document standards are content to specify at best a single precision IEEE-754 floating point number representations.
-
-The research on arbitrary precision arithmetic applied to documents is very sparse; however arbitrary precision arithmetic itself is a very active field of research. Therefore, the second half of this chapter will be devoted to considering the IEEE-754 standard, its advantages and limitations, and possible alternative number representations to allow for arbitrary precision arithmetic.
+The research on arbitrary precision arithmetic applied to documents is very sparse; however arbitrary precision arithmetic itself is a very active field of research. Therefore, the second half of this chapter will be devoted to considering fixed precision floating point numbers as specified by the IEEE-754 standard, possible limitations in precision, and alternative number representations for increased or arbitrary precision arithmetic.
