In this article, we will learn about how to use the DEC2HEX function in Excel.
DEC2HEX function in excel is used to convert decimal representation of numbers of radix 10 to hexadecimal numbers (radix = 16).
The table shown below shows you some of the most used base & their radix of Alpha - numeric characters
|decimal||2||0 - 1|
|octal||8||0 - 7|
|Decimal||10||0 - 9|
|hexadecimal||16||0 - 9 & A - F|
|hexatridecimal||36||0 - 9 & A - Z|
Hexadecimal uses the decimal numbers and six extra symbols
Decimal number is representation of a number of radix 10. 10 digits are used in representation of a decimal number 0 - 9. Where as hexadecimal number representation uses the 10 decimal numbers 0, 1, 2, 3, 4, 5, 6, 7, 8 & 9 and six extra symbols A (= 10 in decimal), B, C, D, E & F. The below table will help you understand better
You can see from the above table that decimal value 10 converted to hexadecimal comes out to be A.
The DEC2HEX function converts the decimal number of radix 10 to the hexadecimal number of radix 16.
Number : decimal number which is to be converted to hexadecimal
[Places] : [optional] number where result expressed upto the number.
The input decimal number to the function should be between - 536870912 to + 536870911. The resulting hexadecimal number will have upto 10 characters (10 bits), where first number express the sign of the number (positive or negative) & Other 9 express the value after the sign. ( 1 for negative & 0 for positive)
To get the hexadecimal number, [places] number must have have sufficient places to express the hexadecimal number or else it returns the #NUM! Error. The decimal negative number is processed using two's complement notation and ignore [places] number if any.
Now let’s get more understanding of the function via using them in some examples.
Here we have some decimal values in hexadecimal Column. We need to convert these decimal numbers to hexadecimal value.
Use the formula in Decimal column:
A2 : number provided to the function as cell reference Values to the DEC2HEX function is provided as cell reference.
The hexadecimal representation of 2 of base 10 (decimal) is 2 of base 16 (hexadecimal).
Now copy the formula to other cells using the Ctrl + D shortcut key.
As you can see here the DEC2HEX function returns the results of the input values.
