## ERF.PRECISE Function

The `ERF.PRECISE`

function in Google Sheets calculates the error function from 0 to a specified value. It is a variation of the ERF function.

### Syntax

```
ERF.PRECISE(lower_bound, [upper_bound])
```

`lower_bound`

: The lower limit of the integral. This is a required parameter.`upper_bound`

: (Optional) The upper limit of the integral. If omitted, it defaults to the lower_bound.

### Examples

**Precise Error Function from 0 to 1**

Calculate the error function from 0 to 1 precisely:

```
=ERF.PRECISE(1)
```

This will output approximately 0.8427.

**Precise Error Function from 0 to 1.5**

Calculate the error function from 0 to 1.5:

```
=ERF.PRECISE(1.5)
```

This will output approximately 0.9661.

**Error Function for a Range**

Calculate the error function from 0.5 to 1.5:

```
=ERF.PRECISE(0.5, 1.5)
```

This will output approximately 0.8427.

### Notes

- ERF.PRECISE is useful for more accurate calculations in statistical applications.
- The function handles both positive and negative values.
