We present an implementation of a MathML authoring tool on the xfy. The
xfy is a software developed in Justsystems Co., that aims at creating an
authoring environment for compound XML documents in a single workspace.
In the context authoring MathML on the xfy, we may utilize computer
algebra systems to input or plot expressions. When the inputs are
inexact polynomials, we will show approximate algebra, such as
approximate-GCD, can be applied to author expressions or draw a curve
with precision $\epsilon$. This feature of the MathML editor can be
useful to author any scientific documents or educational contents for
learning management systems (e.g. Moodle). In this talk, its
implementation and reliability will be discussed.
