This chapter gives you a brief overview about the SWIG implementation of the C++14 standard. There isn't much in C++14 that affects SWIG, however, work has only just begun on adding C++14 support.
Compatibility note: SWIG-4.0.0 is the first version to support any C++14 features.
C++14 added binary integer literals and SWIG supports these. Example:
int b = 0b101011;
