# Significant Figures in quantity?

I am still having trouble grasping significant figures.

How many significant figures would be in this quantity?

$01010.0$

I feel like it is 3, but not quite sure.

• Should be 5. The only reason you would include the 0 to the right of the decimal would be because it was significant. – turkeyhundt Sep 3 '15 at 1:58

It's $5$ significant digits, the zero in front does not mean anything. The $1010$ is all significant because the zero i sandwiched between and there is a decimal point, and the $.0$ is also significant because it tells you we measured to this decimal point.
