e other <tt>bit.*</tt> operations, <tt>bit.tobit()</tt>
converts a cdata number via <tt>int64_t</tt> to <tt>int32_t</tt> and
returns a Lua number.<br>

For <tt>bit.band()</tt>, <tt>bit.bor()</tt> and <tt>bit.bxor()</tt>, the
conversion to <tt>int64_t</tt> or <tt>uint64_t</tt> applies to
<em>all</em> arguments, if <em>any</em> argument is a cdata number.<br>

For all other operations, only the first argument is used to determine
the output type. This implies that a cdata number as a shift count for
shifts an
