The windows.h header file defines the macro max. If the max macro is include it will lead to name collisions with the std::numeric_limits<T>::max() function. One solution is to define NOMINMAX before the inclusion of windows.h. However, that might be a demanding task for a large codebase. Defining the NOMINMAX as global define may also break previous code. Another to solution to the problem is to wrap the numeric_limits function in parenthesis to instruct the compiler to treat it as a function and not a macro. This commit wraps the std::numeric_limits<T>::max() calls in the public interfacing header files, with parenthesis.
