Did you know that Excel limits the number of numbers that appear in a cell, in General format? I discovered that limitation this week, while updating my page on rounding functions in Excel.

您是否知道Excel以常规格式限制单元格中出现的数字数量？ 我在更新Excel中的舍入函数页面时发现了这个限制。

Have you run into this limit? It was something that I hadn't noticed before, and there doesn't seem to be any setting to adjust this.

你遇到这个限制了吗？ 这是我之前从未注意到的事情，而且似乎没有任何设置可以调整此设置。

这些去十一 (These Go to Eleven)

What's the character limit for numbers? Maybe someone at Microsoft is a fan of the movie, This is Spinal Tap, because "these go to eleven".

数字的字符数限制是多少？ 也许Microsoft的某人是这部电影的粉丝， 这就是Spinal Tap ，因为“这些电影达到了11岁”。

In the screen shot below, the full number in cell B2 is shown, because it has 11 characters, including the decimal point. However, the number in cell B3 has an additional 3 characters added, and they don't appear. Even though there is enough space in the column, the number is rounded, and only 11 characters appear.

在下面的屏幕截图中，显示了单元格B2中的完整数字，因为它有11个字符，包括小数点。 但是，单元格B3中的数字又添加了3个字符，并且不会出现。 即使列中有足够的空间，数字也会四舍五入，并且仅显示11个字符。

不只是小数 (Not Just Decimals)

It's not just decimals that are rounded. Integers have their formatting changed to Scientific, if they exceed 11 characters.

舍入的不仅是小数。 如果整数超过11个字符，则将其格式更改为“科学”。

In the next screen shot, the 11 characters show up correctly in cell B2. In cell B3, I added one more number at the end, and the number was switched to Scientific format. Again, there is plenty of room in that column – more than enough to show all the numbers.

在下一个屏幕快照中，单元格B2中正确显示了11个字符。 在单元格B3中，我在末尾添加了一个数字，该数字已切换为科学格式。 同样，该栏中有足够的空间-足以显示所有数字。

更自动的格式化 (More Automatic Formatting)

Excel does other types of automatic formatting too, if the cell is in General format.

如果单元格为常规格式，则Excel也会执行其他类型的自动格式设置。

In the screen shot below, you can see 11-character numbers at their full width, in column B. As the column width is reduced, the numbers are rounded, either by rounding the decimals, or changing to Scientific format.

在下面的屏幕快照中，您可以在B列中看到全角的11个字符。随着列宽度的减小，这些数字将通过四舍五入小数或更改为科学格式进行四舍五入。

Finally, when no format fits, number signs (pound signs / hash tags) are shown in the cell.

最后，当没有合适的格式时，单元格中会显示数字符号(井号/井号标签)。

If there are numbers signs in the cell, you can see the actual value by either of these methods:

如果单元格中有数字符号，则可以通过以下两种方法之一查看实际值：

• click on the cell, and look in the formula bar 单击该单元格，然后在编辑栏中查看
• point to the cell, and see the number in the pop-up tip 指向单元格，然后在弹出的提示中看到数字

停止自动格式化 (Stop the Automatic Formatting)

If you don't want Excel to automatically adjust the number formatting, you can apply a specific format, such as Number, or use a Custom number format. These specific formats will only change to number signs, if the column is too narrow to display them. The formatting won't automatically change, at other times.

如果您不希望Excel自动调整数字格式，则可以应用特定格式，例如Number，或使用Custom number format 。 如果列太窄而无法显示，则这些特定格式将仅更改为数字符号。 在其他时候，格式不会自动更改。

The Custom formats are created and stored in the Format cells dialog box, on the Number tab.

将创建自定义格式并将其存储在“数字”选项卡上的“格式单元格”对话框中。

A few examples of custom formats are shown below.

自定义格式的一些示例如下所示。

You can even use a custom number format to line up numbers that have varying decimal places. The question mark (?) is a placeholder that adds extra spacing, so the numbers line up at the decimal point.

您甚至可以使用自定义数字格式来排列具有不同小数位的数字。 问号(？)是一个占位符，它增加了额外的间距，因此数字在小数点处对齐。

There are more examples of Custom formats on the Microsoft website: Create a Custom Number Format
