<H2>ROUND Round Function
</H2>
<P>
Section: <A HREF=sec_elementary.html> Elementary Functions </A>
<H3>Usage</H3>
Rounds an n-dimensional array to the nearest integer elementwise.
The general syntax for its use is
<PRE>
y = round(x)
</PRE>
<P>
where <code>x</code> is a multidimensional array of numerical type. The <code>round</code>
function preserves the type of the argument. So integer arguments
are not modified, and <code>float</code> arrays return <code>float</code> arrays as
outputs, and similarly for <code>double</code> arrays. The <code>round</code> function
is not defined for <code>complex</code> or <code>dcomplex</code> types.
<H3>Example</H3>
The following demonstrates the <code>round</code> function applied to various
(numerical) arguments. For integer arguments, the round function has
no effect:
<PRE>
--> round(3)
ans =
3
--> round(-3)
ans =
-3
</PRE>
<P>
Next, we take the <code>round</code> of a floating point value:
<PRE>
--> round(3.023f)
ans =
3
--> round(-2.341f)
ans =
-2
</PRE>
<P>
Note that the return type is a <code>float</code> also. Finally, for a <code>double</code>
type:
<PRE>
--> round(4.312)
ans =
4
--> round(-5.32)
ans =
-5
</PRE>
