## Purpose

## Return value

## Arguments

*number*- The number to convert to a given base.*radix*- The base to convert to.*min_length*- [optional] The minimum string length to return, achieved by padding with zeros.

## Syntax

## How to use

The BASE function converts a number to a given base and returns the result as a text string. Base is specified with the *radix* argument.

The BASE function takes three arguments: *number*, *radix*, and *min_length*. *Number* should be an integer between 1 and 2^53. If *number* is negative, BASE returns a #NUM! error. The *radix* argument is used to specify base. *Radix* represents the number of digits used to represent numbers and should be an integer between 2 and 36. The optional *min_length* argument is the minimum string length that BASE should return. When *min_length* is provided, BASE will pad the output with zeros as needed to achieve the length specified.

### Examples

The *radix* argument specifies base and the output from the BASE function is a text string. For example, the formulas below convert the number 13 into text representations of 13 in base 2 (binary), base 10 (decimal), and base 16 (hexadecimal):

```
=BASE(13,2) // returns "1101"
=BASE(13,10) // returns "13"
=BASE(13,16) // returns "D"
```

In the worksheet shown, the input numbers are being converted to three different representations: base 2 (binary), base 10 (decimal), and base 16 (hexadecimal). The formulas in D5, E5, and F5 are:

```
=BASE(B5,2) // base 2
=BASE(B5,10) // base 10
=BASE(B5,16) // base 16
```

The function also offers an optional argument *min_length* which will pad the returned string with zeros when its length is less than the given value. For example, the formulas below require a minimum length of 4:

```
=BASE(3,2,4) // returns "0011" as text
=BASE(10,16,4) // returns "000A" as text
```

### DECIMAL function

The DECIMAL function performs the opposite conversion as the BASE function:

```
=BASE(100,2) // returns "1100100"
=DECIMAL("1100100",2) // returns 100
```

See more on the DECIMAL function here.

### Notes

- The result from BASE is a text string.
- If
*number*is negative, BASE returns a #NUM! error. - BASE expects integers; decimal values are ignored.
