200. decimal sig figs

Posted: Sun Oct 07, 2018 12:43 pm
Is 200. the same as 200.0? I have never seen a decimal without any numbers following it after so I am kind of confused. Also, would it be 3 sig figs or 4?

200. would be 3 sig figs and 200.0 would be 4 sig figs so they would be different

200. would be 3 sig figs, but, if it were just 200 without the decimal then it would only be 1 sig fig. 200. is not the same as 200.0 because then that would be 4 sig figs since the zero does count after the decimal.

200.0 offers more precision than 200., so it follows that 200.0 has one more significant figure than 200.

Usually trailing zeros are not significant, unless they use a decimal point. So 200 will only have one sig fig, but 200. has three. Then, 200.0 has four sig figs.

If your answer is 200 and need to write your answer in 3 sigfigs you can write 200, but if the lowest given value from the question has 4 sigfigs you would need to answer in 4 sigfigs as well. You would write 200.0 which has 4 sigfigs.
