I''m reading through some code from sourceforge for a game called trackballs (never played it though) and I see this in one of the files: virtual void tick(Real)=0; This file doesn''t include any other files and doesn''t typedef any data types... what is the Real data type? aut viam inveniam aut faciam MoonStar Projects

There is no standard datatype called "Real" in C/C++. Either the code you''re looking at doesn''t compile or you''ve missed something somewhere.

Typically "Real" is defined as either a double or floating point type.
