\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 = 
  <float>  - size: [1 1]
 0.00000011920929  
--> 1.0f+eps
ans = 
  <double>  - size: [1 1]
 1.0000000000000002  

\end{verbatim}
