Question

Sig figs question again: the values in a problem call for 3 sig figs, but the answer comes out exactly to 63. Would I use the value 63.0 instead?

Answer 1

0 is not counted as a number unless its after/

Answer 2

To my knowledge, 0 after a decimal point is considered significant.

Answer 3

Answer 4

0.23

here the will be considered.

Answer 6

I don't agree. http://ostermiller.org/calc/significant_figures.html
Put in 63 and input 3 sig figs. It'll say 63.0

Answer 7

In chemistry, having a 0 after the decimal point will change how accurate the data is. 63.000 means its accurate to the thousandths place. 000000000.23 does absolutely nothing to the accuracy of the number, it is still .23.

I'm pretty sure the same rules apply to math as well

Answer 8

Okay, so in order to fit the requirement given in the problem when the values were given to three sig figs, I would have to use 63.0, right?

Answer 9

That is what I would put.
