Understanding the Precision of Numeric Values
Here are three interesting facts about numeric precision in Excel:
-
Excel stores numbers with as much as 15-digit accuracy and converts any digits after
the fifteenth to zeros.
-
Excel drops any digits after the fifteenth in a decimal fraction.
-
Excel uses scientific notation to display numbers that are too long for their cells.
Excel can calculate positive values as large as 9.99E+307 and approximately as small as
1.00E-307. If a formula results in a value outside this range, Excel stores the number as
text and assigns a #NUM! error value to the formula cell.
