+<h1>To cast, casting</h1>
+</center>
+<hr>
+
+If you want to change the 
+<a href="../CONCEPT/data_types.html">datatype</a> of a variable 
+you have to use a technic called <b>cast</b>. For example if want to 
+change an <a href="../CONCEPT/data_types.html#int">int</a> to a 
+<a href="../CONCEPT/data_types.html#float">float</a> 
+you could use the following syntax:
+<p>
+<center>
+<table border=1 width="80%" bgcolor="ivory">
+<tr>
+<td>
+<pre>
+        
+    main()
+    {
+        int var1;
+        float var2;
+
+        var2 = (float)var1;
+    }
+</pre>
+</td>
+</tr>
+</table>
+</center>
+<p>
+As it happens this example would never be used in practice because C 
+would perform the conversion automatically.
+
+What this example does show is the cast operator<b> () </b>. This states, 
+the result of the expression (in this case <b>var1</b>) is to be a  
+data type of <a href="../CONCEPT/data_types.html#float">float</a>.
