The BOOST_PP_GREATER_D macro compares two values for greater magnitude.
It reenters BOOST_PP_WHILE with maximum efficiency.
Usage
BOOST_PP_GREATER_D(d, x, y)
Arguments
- d
-
The next available BOOST_PP_WHILE iteration.
- x
-
The left operand of the comparison.
Valid values range from 0 to BOOST_PP_LIMIT_MAG.
- y
-
The right operand of the comparison.
Valid values range from 0 to BOOST_PP_LIMIT_MAG.
Remarks
If x is greater than y, this macro expands to 1.
Otherwise, it expands to 0.

Sample Code
#include <boost/preprocessor/comparison/greater.hpp>
#include <boost/preprocessor/list/filter.hpp>
#define LIST (1, (2, (3, (4, (5, BOOST_PP_NIL)))))
