How to avoid misleading numbers
For example, if a cell contains .874543, you might format it to appear as 87%. If that cell is used in a formula, the formula uses the full value (.874543), not the displayed value (.87).
In some situations, formatting may cause Excel to display calculation results that appear incorrect, such as when totalling numbers with decimal places. For example, if values are formatted to display two decimal places, you may not see the actual numbers that are used in calculations. But because Excel uses the full precision of the values in its formula, the sum of two values may appear to be incorrect.
Several solutions to this problem are available:
