t one 64&nbsp;bit integer operand results
in another one. The undefined cases for the division, modulo and power
operators return <tt>2LL&nbsp;^&nbsp;63</tt> or

You'll have to explicitly convert a 64&nbsp;bit integer to a Lua
number (e.g. for regular floating-point calculations) with
<tt>tonumber()</tt>. But note this may incur a precision loss.</li>

arithmetic operators apply analogously.<br>
