a runtime error. If you're not sure about the types of the operands, you can safely use the :ref:`is_same() <class_@GlobalScope_method_is_same>` function
|

(but note that it is more strict about types and references). To compare floats, use the :ref:`is_equal_approx() <class_@GlobalScope_method_is_equal_approx>`
|

and :ref:`is_zero_approx() <class_@GlobalScope_method_is_zero_approx>` functions instead.
