Sig Fig Decimal

If you have adding numbers and get 113.9 and the answer can only have 3 sig figs in it, would the answer be 114 or 114.? Or are they the same thing?

Re: Sig Fig Decimal

They would be the same thing! Only if the number in the ones place was a zero would you need a decimal to include it in your sig figs.

ex.
114 - 3 sig figs
110 - 2 sig figs
110. - 3 sig figs

Re: Sig Fig Decimal

114=114.
They both mean the same thing and they both have 3 sig figs

Re: Sig Fig Decimal

They both have three sig figs but I think 114 would be the better answer just because the extra decimal after 114 seems unnecessary.

Re: Sig Fig Decimal

Does that mean 114.0 would be 4 sig figs?

Re: Sig Fig Decimal

114 and 114. have the same number of sig figs.
114 and 114.0 do not have the same number of sig figs.

114 has 3 significant figures.
114.0 has 4 significant figures.

Re: Sig Fig Decimal

As long as you don't add a 0 after . in 114. the answer remains in three significant figures, so either should work!

Re: Sig Fig Decimal

114 and 114. have the same number of sig figs but adding the "." does seem a little redundant so I'd say stick with 114. But 114.0 is not the same as 114 because it has 4 sig figs.

Re: Sig Fig Decimal

114 and 114. have the same amount of significant figures so you could use either.

Re: Sig Fig Decimal

They are the same thing. But if you add a 0 after ".", then it would be different

Re: Sig Fig Decimal

They are the same amount of sig figs! Since they are the same amount of numbers 114 and 114. they are equal in sig figs.
