Your code returns a number of 99.123456789 + 0.00455679 for your calculation. How should you report it in your lab write-up?

Answer: Your code returns a number of 99.123456789 + 0.00455679

Ok, you must see where the error starts to affect your number.

In this case, is in the third decimal.

So you will write 99.123 + - 0.004 da da da.

But you must round your results. In the number you can see that after the 3 comes a 4, so the 3 stays as it is.

in the error, after the 4 comes a 5, so it rounds up.

So the final presentation will be 99.123 + - 0.005

you are discarding all the other decimals because the error "domains" them.
