<H2>EPS Double Precision Floating Point Relative Machine Precision Epsilon
</H2>
<P>
Section: <A HREF=sec_constants.html> Base Constants </A>
<H3>Usage</H3>
Returns <code>eps</code>, which quantifies the relative machine precision
of floating point numbers (a machine specific quantity). The syntax
for <code>eps</code> is:
<PRE>
y = eps
y = eps('double')
y = eps(X)
</PRE>
<P>
First form returns <code>eps</code> for <code>double</code> precision values. For most
typical processors, this value is approximately <code>2^-52</code>, or 2.2204e-16.
Second form return <code>eps</code> for class <code>double</code> or <code>single</code>.
Third form returns distance to the next value greater than X.
<H3>Example</H3>
The following example demonstrates the use of the <code>eps</code> function,
and one of its numerical consequences.
<PRE>
--> eps
ans =
2.2204e-16
--> 1.0+eps
ans =
1.0000
--> eps(1000.)
ans =
1.1369e-13
</PRE>
