# base2dec

Convert text representing number in base N to decimal number

## Syntax

``D = base2dec(baseStr,n)``

## Description

example

````D = base2dec(baseStr,n)` converts `baseStr` to a decimal number and returns it. The input argument `baseStr` represents digits of a base-`n` number using numeric characters and, when `n` is greater than 10, letters. For example, if `n` is 12, then `baseStr` represents the numbers 9, 10, and 11 using the characters `'9'`, `'A'`, and `'B'`, and represents the number 12 as the character sequence `'10'`. Letters can be either uppercase or lowercase.```

## Examples

collapse all

Convert a character vector that represents a base-12 value to a decimal number.

```baseStr = '1B'; D = base2dec(baseStr,12)```
```D = 23 ```

Create a string array that represents multiple octal, or base-8, values.

`baseStr = ["1777" "172" "16"]`
```baseStr = 1x3 string array "1777" "172" "16" ```

Convert the octal values and return a numeric array.

`D = base2dec(baseStr,8)`
```D = 1×3 1023 122 14 ```

## Input Arguments

collapse all

Text representing base-`n` numbers, specified as a character array, cell array of character vectors, or string array.

• If `baseStr` is a character array with multiple rows or a cell array of character vectors, then the output is a numeric column vector.

• If `baseStr` is a string array, then the output is a numeric array that has the same dimensions.

`baseStr` cannot represent a negative number.

Base of input representation, specified as an integer between 2 and 36.

## Tips

• If the input argument `baseStr` represents a value greater than the value returned by `flintmax`, then `base2dec` might not return an exact conversion.
