A significant figure refers to the digits in a number that contribute to its precision, including all the non-zero digits, any zeros between them, and any trailing zeros in the decimal portion. For example, in the number 0.00456, there are three significant figures: 4, 5, and 6. Significant figures are important in scientific measurements and calculations as they convey the certainty of the values and help avoid misleading precision in reporting results. The rules for determining significant figures help ensure consistency in data reporting and calculations.
