MySQL's `CONV(~)` method converts the input number from one base to another and returns it as a string.

# Parameters

1. `N` | `number`

The number to convert.

2. `from_base` | `number`

The base to convert the input from. Range 2 - 36.

3. `to_base` | `number`

The base to convert the input to. Range 2 - 36.

# Return value

String representation of the input number converted to the base specified by `to_base`.

# Examples

To convert `17` from base `10` to base `2`:

``` SELECT CONV(17, 10, 2); +-----------------+| CONV(17, 10, 2) |+-----------------+| 10001 |+-----------------+ ```

Although it is difficult to see, the returned output is a string.

To convert from hexadecimal (base `16`) to base `10`:

``` SELECT CONV('E', 16, 10); +-------------------+| CONV('E', 16, 10) |+-------------------+| 14 |+-------------------+ ```
