# DEC2HEX

The `DEC2HEX` formula is an engineering formula in Google Sheets that converts a decimal number to its hexadecimal equivalent. It is commonly used to convert numbers to a format that is easier to read and work with in certain applications.

## Usage

Use the `DEC2HEX` formula with the syntax shown below, it has 1 required parameter and 1 optional parameter:

Parameters:
1. decimal_number (required):
The decimal number to be converted to hexadecimal. Must be a positive or negative integer or zero.
2. significant_digits (optional):
The number of significant digits to include in the result. Must be a positive integer. If omitted, the result will include the minimum number of digits necessary to represent the number.

## Examples

Here are a few example use cases that explain how to use the `DEC2HEX` formula in Google Sheets.

### Converting decimal numbers to hexadecimal for programming

When working with programming languages such as JavaScript or Python, it is often necessary to represent numbers in hexadecimal format. The `DEC2HEX` formula makes it easy to convert decimal numbers to hexadecimal format.

### Converting RGB color values to hexadecimal

RGB color values are often represented in hexadecimal format, and the `DEC2HEX` formula can be used to convert decimal RGB values to their hexadecimal equivalents.

### Converting decimal numbers to binary for networking

In networking, it is often necessary to represent numbers in binary format. The `DEC2HEX` formula can be used to convert decimal numbers to binary for use in networking applications.

## Common Mistakes

`DEC2HEX` not working? Here are some common mistakes people make when using the `DEC2HEX` Google Sheets Formula:

### Not providing a decimal_number argument

One common mistake is forgetting to provide the decimal_number argument. This will result in an error message. Make sure to always provide the required argument.

### Providing a non-numeric decimal_number argument

Another common mistake is providing a non-numeric decimal_number argument, such as text or an empty cell. This will also result in an error message. Make sure to provide a valid numeric argument.

### Providing a negative significant_digits argument

If you provide a negative significant_digits argument, the function will return an error message. Make sure to provide a non-negative value for the significant_digits argument.

### Providing a significant_digits argument that is too large

If you provide a significant_digits argument that is larger than the number of significant digits in the resulting hexadecimal number, the function will pad the number with zeros. Make sure to provide a reasonable value for the significant_digits argument.

### Not using the correct syntax

Make sure to use the correct syntax for the DEC2HEX function. The decimal_number argument is required, and the significant_digits argument is optional and should be enclosed in square brackets.

The following functions are similar to `DEC2HEX` or are often used with it in a formula:

• `HEX2DEC`

The `HEX2DEC` function converts a signed hexadecimal number to its decimal equivalent. This function is commonly used in engineering calculations where hexadecimal numbers are used to represent signed values.

• `BIN2DEC`

The `BIN2DEC` formula is an engineering formula used to convert a signed binary number to a decimal number. This formula is commonly used in computer science and engineering fields.

• `DEC2BIN`

The `DEC2BIN` formula is used to convert a decimal number to a binary number. This is commonly used in engineering and computer science to represent numbers in their binary form. The formula takes in a decimal number and an optional number of significant digits to include in the binary representation.

• `OCT2DEC`

The `OCT2DEC` function converts a signed octal number to its decimal equivalent. It takes one required parameter, the signed_octal_number, which is the signed octal number you want to convert to decimal. The function returns the decimal equivalent of the signed octal number.
