CEILING.MATH function

This article describes the formula syntax and usage of the CEILING.MATH function in Microsoft Excel.

Description

Rounds a number up to the nearest integer or to the nearest multiple of significance.

Syntax

CEILING.MATH(number, [significance], [mode])

The CEILING.MATH function syntax has the following arguments.

Significance Optional. The multiple to which Number is to be rounded.

Mode Optional. For negative numbers, controls whether Number is rounded toward or away from zero.

Remarks

By default, positive numbers with decimal portions are rounded up to the nearest integer. For example, 6.3 is rounded up to 7.

The Mode argument does not affect positive numbers.

The significance argument rounds the number up to the nearest integer that is a multiple of the significance specified. The exception is where the number to be rounded is an integer. For example, for a significance of 3 the number is rounded up to the next integer that is a multiple of 3.

If Number divided by a Significance of 2 or greater results in a remainder, the result is rounded up.

Example

Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.

Rounds 24.3 up to the nearest integer that is a multiple of 5 (25).

Rounds 6.7 up to the nearest integer (7).

Working with Formulas

In general a formula in Excel can be used directly in the write_formula() method:

However, there are a few potential issues and differences that the user should be aware of. These are explained in the following sections.

Non US Excel functions and syntax

Excel stores formulas in the format of the US English version, regardless of the language or locale of the end-user’s version of Excel. Therefore all formula function names written using XlsxWriter must be in English:

Also, formulas must be written with the US style separator/range operator which is a comma (not semi-colon). Therefore a formula with multiple values should be written as follows:

If you have a non-English version of Excel you can use the following multi-lingual formula translator to help you convert the formula. It can also replace semi-colons with commas.

Formula Results

XlsxWriter doesn’t calculate the result of a formula and instead stores the value 0 as the formula result. It then sets a global flag in the XLSX file to say that all formulas and functions should be recalculated when the file is opened.

This is the method recommended in the Excel documentation and in general it works fine with spreadsheet applications. However, applications that don’t have a facility to calculate formulas will only display the 0 results. Examples of such applications are Excel Viewer, PDF Converters, and some mobile device applications.

If required, it is also possible to specify the calculated result of the formula using the optional value parameter for write_formula() :

The value parameter can be a number, a string, a bool or one of the following Excel error codes:

It is also possible to specify the calculated result of an array formula created with write_array_formula() :

However, using this parameter only writes a single value to the upper left cell in the result array. For a multi-cell array formula where the results are required, the other result values can be specified by using write_number() to write to the appropriate cell:

Dynamic Array support

Excel introduced the concept of “Dynamic Arrays” and new functions that use them in Office 365. The new functions are:

The following special case functions were also added with Dynamic Arrays:

Dynamic arrays are ranges of return values that can change in size based on the results. For example, a function such as FILTER() returns an array of values that can vary in size depending on the the filter results. This is shown in the snippet below from Example: Dynamic array formulas :

Which gives the results shown in the image below. The dynamic range here is “F2:I5” but it could be different based on the filter criteria.

It is also possible to get dynamic array behavior with older Excel functions. For example, the Excel function =LEN(A1) applies to a single cell and returns a single value but it is also possible to apply it to a range of cells and return a range of values using an array formula like <=LEN(A1:A3)>. This type of “static” array behavior is called a CSE (Ctrl+Shift+Enter) formula. With the introduction of dynamic arrays in Excel 365 you can now write this function as =LEN(A1:A3) and get a dynamic range of return values. In XlsxWriter you can use the write_array_formula() worksheet method to get a static/CSE range and write_dynamic_array_formula() to get a dynamic range. For example:

Which gives the following result:

The difference between the two types of array functions is explained in the Microsoft documentation on Dynamic array formulas vs. legacy CSE array formulas. Note the use of the word “legacy” here. This, and the documentation itself, is a clear indication of the future importance of dynamic arrays in Excel.

For a wider and more general introduction to dynamic arrays see the following: Dynamic array formulas in Excel.

The Implicit Intersection Operator, “@”, is used by Excel 365 to indicate a position in a formula that is implicitly returning a single value when a range or an array could be returned.

There is an implicit conversion here of the range of input values, “A1:A3”, to a single value “A1”. Since this was the default behavior of older versions of Excel this conversion isn’t highlighted in any way. But if you open the same file in Excel 365 it will appear as follows:

The result of the formula is the same (this is important to note) and it still operates on, and returns, a single value. However the formula now contains a “@” operator to show that it is implicitly using a single value from the given range.

Finally, if you entered this formula in Excel 365, or with write_dynamic_array_formula() in XlsxWriter, it would operate on the entire range and return an array of values:

If you are encountering the Implicit Intersection Operator “@” for the first time then it is probably from a point of view of “why is Excel/XlsxWriter putting @s in my formulas”. In practical terms if you encounter this operator, and you don’t intend it to be there, then you should probably write the formula as a CSE or dynamic array function using write_array_formula() or write_dynamic_array_formula() (see the previous section on Dynamic Array support ).

A full explanation of this operator is shown in the Microsoft documentation on the Implicit intersection operator: @.

In the section above on Dynamic Array support we saw that dynamic array formulas can return variable sized ranges of results. The Excel documentation refers to this as a “Spilled” range/array from the idea that the results spill into the required number of cells. This is explained in the Microsoft documentation on Dynamic array formulas and spilled array behavior.

Unfortunately, Excel doesn’t store the formula like this and in XlsxWriter you need to use the explicit function ANCHORARRAY() to refer to a spilled range. The example in the image above was generated using the following:

The Excel 365 LAMBDA() function

Note: at the time of writing the LAMBDA() function in Excel is only available to Excel 365 users subscribed to the Beta Channel updates.

Consider the following Excel example which converts the variable temp from Fahrenheit to Celsius:

This could be called in Excel with an argument:

Or assigned to a defined name and called as a user defined function:

This is similar to this example in Python:

The formula is written as follows:

Note, that the parameters in the LAMBDA() function must have a “_xlpm.” prefix for compatibility with how the formulas are stored in Excel. These prefixes won’t show up in the formula, as shown in the image.

The LET() function is often used in conjunction with LAMBDA() to assign names to calculation results.

Formulas added in Excel 2010 and later

When written using write_formula() these functions need to be fully qualified with a _xlfn. (or other) prefix as they are shown the list below. For example:

These functions will appear without the prefix in Excel:

Alternatively, you can enable the use_future_functions option in the Workbook() constructor, which will add the prefix as required:

If the formula already contains a _xlfn. prefix, on any function, then the formula will be ignored and won’t be expanded any further.

Enabling the use_future_functions option adds an overhead to all formula processing in XlsxWriter. If your application has a lot of formulas or is performance sensitive then it is best to use the explicit _xlfn. prefix instead.

The dynamic array functions shown in the Dynamic Array support section above are also future functions:

However, since these functions are part of a powerful new feature in Excel, and likely to be very important to end users, they are converted automatically from their shorter version to the explicit future function version by XlsxWriter, even without the use_future_function option. If you need to override the automatic conversion you can use the explicit versions with the prefixes shown above.

Using Tables in Formulas

Worksheet tables can be added with XlsxWriter using the add_table() method:

If you need to know the name of the table, for example to use it in a formula, you can get it as follows:

When used in a formula a table name such as TableX should be referred to as TableX[] (like a Python list):

Dealing with formula errors

Finally if you have completed all the previous steps and still get a #NAME? error you can examine a valid Excel file to see what the correct syntax should be. To do this you should create a valid formula in Excel and save the file. You can then examine the XML in the unzipped file.

The following shows how to do that using Linux unzip and libxml’s xmllint to format the XML for clarity:

_xlfn в microsoft office. Что это такое?

Икселефэн, прямо шершеляфам.

Когда я работал в файле по захвату мирового господства и формула в ячейке достигла небывалой толщины, успев понтонуться перед друзьями какую я мегаформулу накалякал, а потом сохранил и снова открыл, я увидел болт. Самый настоящий черный болт из браззерс.

В этой формуле одна из функций была заменена на другую с префиксом _xlfn.

Давай разбираться, гуглить. Как ни странно, помог сам хелп майкрософта. Обычно официальные хелпы можно смело сливать в унитаз, и решение находишь от других пользователей, а тут прям удивительно.

Я понял, что я использовал функцию, которая якобы не поддерживается в моем офисе. Но как блеать? Если она у меня выпадала в списке, а после следующего раза она пропала?

Если конкретно, то я говорю про функцию СЦЕП. Сначала я пользовался ею, а при следующем запуске вместо нее появилось _xlfn.CONCAT.

Видя эту хуиту, я так понял, что префиксом _xlfn офис сказал, что функция не поддерживается и предложил альтернативу — конкатенацию (CONCAT). Я правда не вдуплил, почему ее, т.к. там есть ближайшая альтернатива — СЦЕПИТЬ.

Давай проверять наличие функции СЦЕП. И реально, теперь она пропала, вместо нее выводится СЦЕПИТЬ.

Короче, заменил СЦЕП на СЦЕПИТЬ (на более старую) и всё заработало.

П.С. я был готов даже купить лицензионный офис, но без ста грамм не разберешься, где и чего покупать. А где-то вообще говорится, что десктопная версия офис 2019 это вообще не то, что офис 365 по подписке. Короче мутная херня какая-то.
