I need a 64 bit number, to create a bitboard: http://pages.cs.wisc.edu/~psilord/blog/data/chess-pages/rep.html
And be able to use binary operations like | or &. The integer of godot is 64 bit but it is signed, do you know any way to convert it to unsigned?
Precisely, I need to pass from this:
-9223372036854775808 to 9223372036854775807
0 to 18446744073709551615
