\section{FEPS Single Precision Floating Point Relative Machine Precision Epsilon}

\subsection{Usage}

Returns \verb|feps|, which quantifies the relative machine precision
of floating point numbers (a machine specific quantity).  The syntax
for \verb|feps| is:
\begin{verbatim}
   y = feps
\end{verbatim}
which returns \verb|feps| for \verb|single| precision values. For most
typical processors, this value is approximately \verb|2^-24|, or 5.9604e-8.
\subsection{Example}

The following example demonstrates the use of the \verb|feps| function,
and one of its numerical consequences.
\begin{verbatim}
--> feps

ans = 

 1.1921e-07 

--> 1.0f+eps

ans = 

    1.0000 


\end{verbatim}
