To ensure precision, how many digits should be used when dealing with constants?

My TA told our discussion to use the exact number of sig figs given to you on Lavelle's formula sheet when solving problems with constant. He told our class not to round them, but rounding will not make a huge difference in your answer if you do every thing else correctly.

Seconding Nicole's answer. Using all the figures that are provided for constants in the sheet ensures that you won't have rounding errors for your final answer.
