# ROUNDDOWN

The **ROUNDDOWN** function rounds a number down toward zero to a specified number of decimal places. It always reduces the value regardless of the digit that follows and is useful in scenarios where conservative estimates are required.

### Syntax

```javascript
ROUNDDOWN(value, significance)
```

### Arguments

value -The number to be rounded (Required).

significance - The number of decimal places to round off (Optional).

### Example

```javascript
ROUNDDOWN(Actuals,2) //Rounds the Actuals to 1 decimal place
```

In the example below, the *ROUNDDOWN* measure is created using the **ROUNDDOWN** function, which rounds the *Actuals* values down toward zero to one decimal place.
