The 'computerized' methods store the results using significant digits. In other words, they can only hold so many digits. So when you have a number 16/113, you can hold more digits after the decimal point compared to 335/113. Think about only the first few digits:

0.1415929 - 0.1415926 != 0
3.141592-3.141592 = 0 (very inaccurate)

If you're interested in how to get more accurate numbers, you can read about "numerical approximation"

Anyways, very interesting problem!
