The BOOST_PP_LESS macro compares two values for lesser magnitude.

Usage

BOOST_PP_LESS(x, y)

Arguments

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 less than y, this macro expands to 1.  Otherwise, it expands to 0.
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_LESS_D in such a situation.
