/** \def BOOST_VMD_IS_NUMBER(sequence)
|
|
\brief Tests whether a sequence is a Boost PP number.
|
|
The macro checks to see if a sequence is a Boost PP number.
|
A Boost PP number is a value from 0 to BOOST_PP_LIMIT_MAG.
|
|
sequence = a possible number
|
|
returns = 1 if the sequence is a Boost PP number,
|
0 if it is not.
|
|
If the input is not a VMD data type this macro could lead to
|
a preprocessor error. This is because the macro
|
uses preprocessor concatenation to determine if the input
|
is a number once it is determined that the input does not
|
start with parenthesis. If the data being concatenated would
|
lead to an invalid preprocessor token the compiler can issue
|
a preprocessor error.
