The BOOST_PP_NOR macro expands to the logical NOR of its operands.

#### Usage

BOOST_PP_NOR(p, q)

#### Arguments

p
  The left operand of the operation. Valid values range from 0 to BOOST_PP_LIMIT_MAG.
q
  The right operand of the operation. Valid values range from 0 to BOOST_PP_LIMIT_MAG.

#### Remarks

If both p and q are both 0, this macro expands to 1. Otherwise, it expands to 0.
This macro performs a boolean conversion on each operand before performing the logical NOR operation. If that conversion is not necessary, use BOOST_PP_BITNOR instead.

    BOOST_PP_NOR(4, 0) // expands to 0
    BOOST_PP_NOR(0, 0) // expands to 1
