The BOOST_PP_MAX macro expands to the greater of its two arguments.

Usage

BOOST_PP_MAX(x, y)

Arguments

x
The first operand.  Valid values range from 0 to BOOST_PP_LIMIT_MAG.
y
The second operand.  Valid values range from 0 to BOOST_PP_LIMIT_MAG.

Remarks

This macro returns the greater of its two arguments or the value of both arguments if they are equal.
Previously, this macro could not be used inside BOOST_PP_WHILE.  There is no longer any such restriction.  It is more efficient, however, to use BOOST_PP_MAX_D in such a situation.
