EXAMPLE
Find the first occurrence of 0 (the first whole number) in the digits of sqrt(2) (only 35 digits in this illustration):
14142135623730950488016887242096980..., and replace it with a space:
1414213562373 950488016887242096980... Repeat the process with the next whole number, 1:
414213562373 950488016887242096980... Then 2:
414 13562373 950488016887242096980... Then 3:
414 1 562373 950488016887242096980... Then 4,5,6,7, etc., until the first occurrence of every counting number is eliminated from the digits of sqrt(2).
1 3 4 8 9 ... Then consolidate gaps between the remaining digits into a single comma:
1,3,4,8,9,80,9,69,0,7,7,8,2,0,5,3, ... to produce the first terms in the whole number sieve of sqrt(2).
