# 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.

## Usage

Use the `DEC2BIN` formula with the syntax shown below, it has 1 required parameter and 1 optional parameter:

Parameters:
1. decimal_number (required):
The decimal number to convert to binary. Must be a positive integer.
2. significant_digits (optional):
Optional. The number of significant digits to include in the binary representation. Must be a positive integer.

## Examples

Here are a few example use cases that explain how to use the `DEC2BIN` formula in Google Sheets.

### Convert decimal IP addresses to binary

In network engineering, IP addresses are commonly represented in binary form. The `DEC2BIN` formula can be used to quickly convert decimal IP addresses to binary.

### Convert decimal RGB values to binary

In computer graphics, RGB values are commonly represented in binary form. The `DEC2BIN` formula can be used to quickly convert decimal RGB values to binary.

### Check parity of binary numbers

In computer science, it is common to check the parity of binary numbers. The `DEC2BIN` formula can be used to convert decimal numbers to binary, which can then be used to check parity.

## Common Mistakes

`DEC2BIN` not working? Here are some common mistakes people make when using the `DEC2BIN` Google Sheets Formula:

### Wrong number of arguments

The DEC2BIN formula requires at least one argument, the decimal number to be converted to binary. If the optional argument 'significant_digits' is used, it must be the second argument.

### Incorrect argument type

The 'decimal_number' argument must be a number. If a non-numeric value is used, the formula will return an error.

### Invalid significant digits

The 'significant_digits' argument, if used, must be a positive integer. If a decimal or non-numeric value is used, the formula will return an error.

### Out of range decimal number

If the 'decimal_number' argument is greater than 511 or less than -512, the formula will return an error.

### Incorrect binary output

If the 'significant_digits' argument is used, the formula may return an incorrect binary output if the 'significant_digits' value is too small for the decimal number being converted.

The following functions are similar to `DEC2BIN` or are often used with it in a formula:

• `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.

• `HEX2BIN`

The `HEX2BIN` function is an Engineering function that converts a signed hexadecimal number to a signed binary number. It returns a text string and is commonly used in computer science and engineering fields.

• `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.
