However, you can change the precision of calculations so that Excel uses the displayed value instead of the stored value when it recalculates formulas.
As calculation proceeds, you can choose commands or perform actions such as entering numbers or formulas.
If you later choose to calculate with full precision, the original underlying values cannot be restored.
Although Excel limits precision to 15 digits, that doesn't mean that 15 digits is the limit of the size of a number you can store in Excel.
Note: If a worksheet contains a formula that is linked to a worksheet that has not been recalculated and you update that link, Excel displays a message stating that the source worksheet is not completely recalculated.
You can change the display of the date to another format (for example, to "22-Jun-2008"), but changing the display of a value on a worksheet does not change the stored value.
Any digits to the right of the 15th digit will be zeros.
For example, 1234567.890123456 has 16 digits (7 digits before and 9 digits after the decimal point).
To use formulas efficiently, there are three important considerations that you need to understand: Calculation is the process of computing formulas and then displaying the results as values in the cells that contain the formulas.
To avoid unnecessary calculations that can waste your time and slow down your computer, Microsoft Excel automatically recalculates formulas only when the cells that the formula depends on have changed.
You can use Goal Seek when you know the desired result of a single formula but not the input value the formula needs to determine the result.
