By 2015 , it was possible to extend Pi 's decimal representation to over 13.3 trillion ( 1013 ) digits when combined with increasing computational power .
In the 20th and 21st centuries , mathematicians and computer scientists discovered new approaches that , when combined with increasing computational power , extended the decimal representation of to , , over 13.3 trillion ( 1013 ) digits.y-cruncher - A Multi-Threaded Pi Program Practically all scientific applications require no more than a few hundred digits of , and many substantially fewer , so the primary motivation for these computations is the human desire to break records .
