How many sig figs are used in standard deviation?

Is there a set number of sig figs (like 2 s.f. or 2 numbers after the decimal place), or it depends on the smallest number of sig figs in my data (ex: 4.124, 5.29458, 3.8, 4.395 the standard deviation would have 2 s.f. since 3.8 has the least # of sig figs?)

Thank you.
