.The operands shall be of integral or unscoped enumeration type
.Given the coefficients
xi and yi
of the base-2 representation ([basic.fundamental])
of the converted operands x and y,
the coefficient ri
of the base-2 representation of the result r
is 1 if at least one of xi and yi is 1, and 0 otherwise.[
Note 1:
The result is the bitwise inclusive
or function of the operands
