<P><B><I>divides</B></I> is a binary function object.  Its <SAMP>operator()</SAMP> returns the result of dividing <SAMP>x</SAMP> by <SAMP>y</SAMP>.  You can pass a <B><I>divides</B></I> object to any algorithm that requires a binary function.  For example, the <A HREF="tra_4787.htm"><B><I>transform</B></I></A> algorithm applies a binary operation to corresponding values in two collections and stores the result.   <B><I>divides</B></I> would be used in that algorithm in the following manner:</P>
<PRE>vector&#60;int> vec1;</PRE>
<PRE>vector&#60;int> vec2;
vector&#60;int> vecResult;
.

transform(vec1.begin(), vec1.end(),          vec2.begin(), vecResult.begin(), </PRE>
<PRE>          <B>divides</B>&#60;int>());
</PRE><P>After this call to <A HREF="tra_4787.htm"><B><I>transform</B></I></A>, <SAMP>vecResult[n]</SAMP> will contain <SAMP>vec1[n]</SAMP> divided by <SAMP>vec2[n]</SAMP>.</P>
