What are the rules for significant figures when you're switching between calculations of pH and molar concentrations?

From the textbook, pg 472: "The number of digits following the decimal point in a pH value is equal to the number of significant figures in the corresponding molar concentration, because the digits preceding the decimal point simply report the power of 10 in the data (as in log 105 # 5)."
