MySQL's `ROUND(~)` method returns the input argument rounded to the specified number of decimal places.

NOTE

A value with a fractional part of .5 or greater is rounded up to the next integer if positive or down to the next integer if negative.

# Parameters

1. `X` | `number`

The number to perform the rounding on.

2. `D` | `number` | `optional`

The number of decimal places to round the input value to. Defaults to `0`.

NOTE

This number can be negative to round to digits left of the decimal point. For example, `D=-1` would round the number to the nearest tens.

# Return value

The input number rounded to the specified number of decimal places.

# Examples

To round to zero decimal places (default):

``` SELECT ROUND(-5.52); +--------------+| ROUND(-5.52) |+--------------+| -6 |+--------------+ ```

To round to `1` decimal place:

``` SELECT ROUND(-5.44, 1); +-----------------+| ROUND(-5.44, 1) |+-----------------+| -5.4 |+-----------------+ ```

To round to `-1` decimal place (i.e. nearest tens value):

``` SELECT ROUND(123, -1); +----------------+| ROUND(123,-1) |+----------------+| 120 |+----------------+ ```
