Why is %b deprecated in Printf?
<p>The <a href="http://caml.inria.fr/pub/docs/manual-ocaml/libref/Printf.html" rel="nofollow">Printf module</a> API details the type conversion flags, among them:</p>

<pre><code>%B: convert a boolean argument to the string true or false
%b: convert a boolean argument (deprecated; do not use in new programs).
</code></pre>

<p>But it does not say why <code>%b</code> is deprecated. Why is <code>%B</code> better than <code>%b</code>?</p>
