function TestBits(const Value: Word; const Mask: Word): Boolean; overload;
function TestBits(const Value: Cardinal; const Mask: Cardinal): Boolean; overload;
function TestBits(const Value: Integer; const Mask: Integer): Boolean; overload;
function TestBits(const Value: Int64; const Mask: Int64): Boolean; overload;

Parameters
