I think you are confusing what is displayed with what is computed: 20000000/21 # [1] 952381 print(20000000/21,17) # [1] 952380.9523809524 55555555/23 # [1] 2415459 print(55555555/23,17) # [1] 2415458.913043478 (20000000/21)*21 # [1] 2e+07 print((20000000/21)*21,17) # [1] 2e+07 (55555555/23)*23 # [1] 55555555 print((55555555/23)*23,17) # [1] 55555555 Your "numbers bigger than 10 000 000" corresponds to the default display of results to 7 significant figures. If (as in the above print() statements) you increase this, you get more "reasonable"-looking results.
