Decimal to hex excel

DEC2HEX function

This article describes the formula syntax and usage of the DEC2HEX function in Microsoft Excel.

Description

Converts a decimal number to hexadecimal.

Syntax

The DEC2HEX function syntax has the following arguments:

Number Required. The decimal integer you want to convert. If number is negative, places is ignored and DEC2HEX returns a 10-character (40-bit) hexadecimal number in which the most significant bit is the sign bit. The remaining 39 bits are magnitude bits. Negative numbers are represented using two’s-complement notation.

Places Optional. The number of characters to use. If places is omitted, DEC2HEX uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).

If Number is 549,755,813,887, DEC2HEX returns the #NUM! error value.

If Number is non-numeric, DEC2HEX returns the #VALUE! error value.

If the result of DEC2HEX requires more than the number of specified Places characters, it returns the #NUM! error value.
For example, DEC2HEX(64,1) returns the error value because the result (40) requires two characters.

If Places is not an integer, the value of Places is truncated.

If Places is non-numeric, DEC2HEX returns the #VALUE! error value.

If Places is negative, DEC2HEX returns the #NUM! error value.

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.

Converts decimal value 100 to hexadecimal with 4 characters («padded» with two leading zeros).

Converts decimal value -54 to hexadecimal

Converts decimal value 28 to hexadecimal.

Returns the #NUM! error value because the result (40) requires 2 character places.

Функция ДЕС.В.ШЕСТН

В этой статье описаны синтаксис формулы и использование функции ДЕС.В.ШЕСТН в Microsoft Excel.

Описание

Преобразует десятичное число в шестнадцатеричное.

Синтаксис

Аргументы функции ДЕС.В.ШЕСТН описаны ниже.

Число — обязательный аргумент. Преобразуемое десятичное число. Если оно отрицательное, то разрядность игнорируется и функция ДЕС.В.ШЕСТН возвращает 10-значное (40-битное) шестнадцатеричное число, в котором самый старший бит является знаковым битом. Остальные 39 бит являются битами значения. Отрицательные числа представляются в дополнительных кодах.

Разрядность Необязательный. Количество знаков в записи числа. Если разрядность опущена, функция ДЕС.В.ШЕСТН использует минимально необходимое количество знаков. Разрядность используется, чтобы приписать возвращаемому значению ведущие нули.

Замечания

Если число 549 755 813 887, то DEC2HEX возвращает #NUM! значение ошибки #ЗНАЧ!.

Если число не является числом, то DEC2HEX возвращает #VALUE! значение ошибки #ЗНАЧ!.

Если для результата DEC2HEX требуется больше количества знаков Знаков знаков Знаков после заданного числа знаков Знаков после заданного числа знаков, возвращается #NUM! значение ошибки #ЗНАЧ!.
Например, DEC2HEX(64;1) возвращает значение ошибки, так как для результата (40) требуется два знака.

Если значение аргумента «разрядность» не является целым числом, оно усекается.

Если число не является числом, то DEC2HEX возвращает #VALUE! значение ошибки #ЗНАЧ!.

Если «количество» отрицательное, то DEC2HEX возвращает #NUM! значение ошибки #ЗНАЧ!.

Пример

Скопируйте образец данных из следующей таблицы и вставьте их в ячейку A1 нового листа Excel. Чтобы отобразить результаты формул, выделите их и нажмите клавишу F2, а затем — клавишу ВВОД. При необходимости измените ширину столбцов, чтобы видеть все данные.

Преобразует десятичное число 100 в шестнадцатеричное из 4 знаков (с «приписанными» двумя ведущими нулями).

Преобразует десятичное значение -54 в шестнадцатеричное

Преобразует десятичное значение 28 в шестнадцатеричное.

Возвращает #NUM! из-за того, что для результата (40) требуется 2 знака.

Converting to Hexadecimal

Written by Allen Wyatt (last updated February 15, 2020)
This tip applies to Excel 97, 2000, 2002, and 2003

If you do any programming, you know how important hexadecimal numbers are. Hexadecimal numbers are used to represent values that can be easily understood by both humans and programming languages. In the hexadecimal numbering system, each digit can vary between 0 and F. Thus, 0 through 9 are the same as in our decimal numbering system, and A through F are converted to 10 through 15 in decimal.

How can Excel help with hexadecimal numbers? It includes a worksheet function that allows you to easily convert a number from decimal to hexadecimal. For instance, let’s say you have a decimal value in E3. If you wanted to know the hexadecimal equivalent, you would use the following:

If the value in E3 was 123, the result of the above formula would be 7B. The DEC2HEX worksheet function can be used to convert any decimal values between -549,755,813,888 and 549,755,813,887.

Once the conversion is done, the value in the cell is considered text. This means that you cannot use the results of DEC2HEX in a numeric formula.

How to use the Excel DEC2HEX Function

We have some very effective functions when it comes to working with numbers in Excel. DEC2HEX is one such function. It takes a decimal number and converts it to its hexadecimal counterpart. In this tutorial, we will learn how to use the DEX2HEC function in Excel.

Figure 1. Example of How to Use the DEC2HEX Function in Excel

Syntax for DEC2HEX Function

• Number: Required. This is the decimal number to convert to its hexadecimal equivalent.
• [places]: Optional. Rounds up the output number with zeros up to the digits specified. If we omit it, DEC2HEX returns the minimum number of characters needed to show the number.

Setting up Data

The following data set has some sample decimal numbers. Column A contains the numbers.

Figure 2. The Sample Data Set

To convert these numbers to hexadecimal in column B:

• We need to click cell B2 with the mouse.
• Assign the formula =DEC2HEX(A2,7) to the formula bar of cell B2.
• Press Enter .

Figure 3. Example of Applying the DEC2HEX Function

• Assign the formula =DEC2HEX(A3) to cell B3. Press Enter and drag the fill handle from cells B3 to B5.

Column B will now have the hexadecimal representation of the decimal numbers in column A. Cell B2 has the formula with the places argument 7. This rounds up the output 600D with 0’s in the first three digits.

Notes

• The DEC2HEX function requires a valid input of a decimal number within the range [ -2^39, 2^39 – 1] . Otherwise it returns a #NUM! error.
• DEC2HEX returns a #VALUE! error if the number is non numeric.
• It returns a #NUM! Error if the result of DEC2HEX requires more numbers than the places argument.
• Excel truncates the value of the places argument if it is not an integer .
• DEC2HEX returns a #VALUE! error if places is non numeric . It returns a #NUM! error if places is negative .

How to format a Microsoft Excel 2007 cell in hexadecimal?

I would like a format a cell in Microsoft Excel 2007 in hexadecimal but am not finding how to do this.

Is there a built-in way to change the base from 10 to 16 for a cell?

6 Answers 6

As mentioned earlier, the formula =DEC2HEX(A1) converts to hex, and DEC2HEX(A1,8) converts to hex with 0 prefix to denote 32 bits. While adding the leading 0’s makes the numbers more readable, especially if you use a fixed point font, the hex and decimal versions can get mixed up when all of the digits in the number happen to be 0-9 (e.g. 327701=50015).

An improvement is to add the «0x» prefix. There are 2 ways to do this. =»0x»&DEC2HEX(A1,8) will do the trick, but it changes the field to a text field, so it can no longer easily be used in formulas. Another method is to use a custom format. If you apply the custom format «0x»@ to the cell, then the value of the cell can still be used in an equation. Examples:

However, large numbers with varying digits can still be hard to read, so I like to put commas into decimal numbers and «_»s into hex numbers. First you need to get the upper and lower 16 bits of the number. The upper 16 bits of a 32-bit number can be retrieved with = INT( A1 / 2^16 ). Dividing by 2^16 acts like a right shift of 16 bits, and the INT removes the fractional remainder. MOD can be used to get the lower 16 bits of any 32 or 64-bit number; =MOD(A1, 2^16). The MOD effectively gets the remainder back, which is the lower 16 bits. Here is a table that shows this in action.
