The second digit in the given number 2648 is 6 Because the number 6 is greater than 5, therefore it can be rounded as 7 Therefore, the number 2648 with four significant figures can be written as 2700 in two significant figures.Instructions Enter the number that you wish to have formatted with significant figures and the calculator will display the formattedversion in the box to the left.Results are shown only with as many significantfigures as the quantity that was entered.
Scientific notation may be used forlarge results or if the number of significant digits would be ambiguous otherwise.The calculator follows proper rounding rules for scientific purposes. A significant figure is any non-zero digit or any embedded or trailing zero. The number may be rounded or padded with zeros to give it thecorrect number of significant figures. When multiplying values together, your result isonly as significant as your least significant value. The least significant decimal is the place that holds the last significant digit. For example,243.3s least significant decimal is -1 (10-1 for the 110ths place). ![]() It rounds up if the next digit is greater than five.Rounds down if the next digit is less than five. If the next digit is five it rounds up half the time and downhalf the time based on whether the previous digit is even or odd. This ensures that cumulative rounding errors donot skew the data.

Multiplication ( or ) and division ( or ) round by the least number of significant figures. Logarithm (log, ln) uses the inputs number of significant figures as the results number of decimals. Antilogarithm (nx.y) uses the powers number of decimals (mantissa) as the results number of significant figures. Exponentiation (nx) only rounds by the significant figures in the base. To count trailing zeros, add a decimal point at the end (e.g. ![]() Rounds when appropriate, after parentheses, and on the final step.
