The BOOST_PP_NOT macro performs a logical NOT on its operand.

#### Usage

BOOST_PP_NOT(x)

#### Arguments

x
  The value to be converted. Valid values range from 0 to BOOST_PP_LIMIT_MAG.

#### Remarks

If x is non-zero, this macro expands to 1. Otherwise, it expands to 0.
This macro performs a boolean conversion on its operand before performing the logical NOT operation. If that conversion is not necessary, use BOOST_PP_COMPL instead.

#### Requirements

Header: <boost/preprocessor/logical/not.hpp>

#### Sample Code

    #include <boost/preprocessor/logical/not.hpp>

    BOOST_PP_NOT(55) // expands to 0
    BOOST_PP_NOT(0) // expands to 1
