 Initial plans for the machine called for it to have a precision of 5 decimal digits, but Cunningham's input compelled the inventors to design it with a precision of 10 decimal digits.From 1945 to 1946, Cunningham served on the BRL's Computations Committee at Aberdeen Proving Grounds in Maryland, a group established as part of the Ballistics Research Laboratory to prepare the ENIAC for utilization following its completion the Moore School; the other Computations Committee members were Haskell Curry, Derrick Henry Lehmer, and Franz Alt.His duties included supervision of the laboratory's shop of IBM punched card calculating equipment, which was busy calculating ballistics trajectories, and writing sample problem specifications for benchmarking the ENIAC.
