About Number Formatting
By default, all cells use the General number format. This format is basically “what you type is what you get.” But if the cell isn't wide enough to show the entire number, the General format rounds numbers with decimals and uses scientific notation for large numbers. In many cases, the General number format works just fine, but most people prefer to specify a different number format for consistency.
The key thing to remember about number formatting is that it affects only how a value is displayed. The actual number remains intact, and any formulas that use a formatted number use the actual number.
