Question: How does the choice of decimal places affect a final answer in computation?
 
Yours Truly answers: The choice does not affect the final answer at all. For example, suppose we set the number of decimal places to two:

Now, compute 1/3 which is displayed as 0.33. But, if we multiply this by 3, the next display shows 1:

This means that, even though the display shows only two decimal places, TI-83 continues to use the true value of 1/3 internally for further computations.
