Abstract
Early in June, 1949, Professor John von Neumann expressed an interest in the possibility that the ENIAC might sometime be employed to determine the value of π and e to many decimal places with a view toward obtaining a statistical measure of the randomness of distribution of the digits, suggesting the employment of one of the formulas:
π/4 = 4 arctan 1/5 – arctan 1/239
π/4 = 8 arctan 1/10 – 4 arctan 1/515 – arctan 1/239
π/4 = 3 arctan 1/4 +arctan 1/20 + arctan 1/1985
