# 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.

## Usage

Use the `BIN2DEC` formula with the syntax shown below, it has 1 required parameter:

Parameters:
1. signed_binary_number (required):
The signed binary number that you want to convert to decimal. This must be a string that contains no more than 10 characters. The leftmost character is the sign bit, with 0 indicating a positive number and 1 indicating a negative number.

## Examples

Here are a few example use cases that explain how to use the `BIN2DEC` formula in Google Sheets.

### Converting binary numbers to decimal

You can use the `BIN2DEC` formula to convert binary numbers to decimal. This is useful for working with binary data in engineering and computer science applications.

### Working with signed binary numbers

The `BIN2DEC` formula is particularly useful for working with signed binary numbers, which are commonly used in computer science and engineering applications.

## Common Mistakes

`BIN2DEC` not working? Here are some common mistakes people make when using the `BIN2DEC` Google Sheets Formula:

### Invalid binary number

The input must be a valid signed binary number. Make sure the input contains only 0s and 1s and starts with a minus sign (-) if it is negative.

### Missing argument

The BIN2DEC function requires one argument. Make sure you are providing a valid signed binary number as input.

### Invalid data type

The input must be a valid signed binary number. Make sure the input is formatted as text or a number.

### Negative exponent

If the input contains a negative exponent, the result may be inaccurate. Consider using a different formula for converting binary to decimal in this case.

### Overflow error

If the input is too large, the function may return an error or an incorrect result. Consider using a different formula or breaking the input into smaller chunks.

The following functions are similar to `BIN2DEC` or are often used with it in a formula:

• `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.

• `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.

• `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.
