 <p>In the example above, the LLVM builder class is starting to show its value.  
 IRBuilder knows where to insert the newly created instruction, all you have to
-do is specify what instruction to create (e.g. with <tt>CreateAdd</tt>), which
+do is specify what instruction to create (e.g. with <tt>CreateFAdd</tt>), which
 operands to use (<tt>L</tt> and <tt>R</tt> here) and optionally provide a name
 for the generated instruction.</p>
