5.6.9.8.3 Or Operator

The Or operator performs a bitwise disjunction on its operands.

 or-operator-expression = expression "or" expression 

Runtime semantics:

§ The operation to produce the result is determined based on the values of the operands, as follows:

Left Operand Value	Right Operand Value	Result
Integral value	Integral value	Bitwise Or of operands
Integral value	Null	Left operand
Null	Integral value	Right operand
Null	Null	Null

 

§ If a bitwise Or of the operands is indicated, the result is produced by generating a corresponding result bit for each pair of identically positioned bits in the implementation format of the operands according to the following table:

Left Operand Bit	Right Operand Bit	Result Bit
0	0	0
0	1	1
1	0	1
1	1	1
