		Any numeric or boolean type.
	##//rhs//##
		The right-hand side expression.
	##//T2//##
		Any numeric or boolean type.
	##//Ret//##
		A numeric or boolean type (varies with ##//T1//## and ##//T2//##).

{{fbdoc item="ret"}}
	Returns the short circuit-or (inclusive disjunction) of the two operands.

{{fbdoc item="desc"}}
	This operator evaluates the left hand side expression.  If the result is nonzero, then ##-1## (true) is immediately returned.  If the result is zero then the right hand side is evaluated, and the logical result from that is returned, returning ##-1## (true) for a nonzero value or ##0## (false) for zero.
	(for conversion of a boolean to an integer, false or true boolean value becomes 0 or -1 integer value)

	The truth table below demonstrates all combinations of a short circuit-or operation, the '-' denotes that the operand is not evaluated.

	{{table columns="3" cellpadding="2" cells="Lhs Value;Rhs Value;Result;0;0;0;0;nonzero;-1;nonzero;-;-1"}}

	Short-circuiting is performed - only expressions needed to calculate the result are evaluated.
	
	The return type is almost always an ##[[KeyPgInteger Integer]]##, of the value ##0## or ##-1##, denoting false and true respectively. Except if the left and right-hand side types are both ##[[KeyPgBoolean Boolean]]##, then the return type is also ##[[KeyPgBoolean Boolean]]##.

	This operator cannot be overloaded for user-defined types.
