# Random Double (RandomDoubleGenerator)

The [Random Double](https://docs.tonic.ai/app/generation/generators/generator-reference/random-double) generator generates a random double number between the specified minimum (inclusive) and maximum (exclusive).

## Link object structure <a href="#generator-api-random-double-link-object" id="generator-api-random-double-link-object"></a>

The Random Double generator does not support linking or consistency. You cannot configure differential privacy.

The `metadata` object is populated from the [`ContinuousDistributionMetadata`](https://app.tonic.ai/apidocs/index.html#/models/ContinuousDistributionMetadata) object. You specify the minimum and maximum values.

```json
{
  "schema": "string",
  "table": "test",
  "column": "number-column",
  "path": "string",  //JSON fields only
  "dataType": "string",  //MongoDB, Amazon DynamoDB, and JSON fields only
  "metadata": {
    "presetId": "string",
    "generatorId": "RandomDoubleGenerator",
    "min": double,
    "max": double,
    "encryptionProcessor": "x-on", //To use configured Structural data encryption
    "customValueProcessor": "string"  //If custom value processor applied
  }
}
```

## Example replacement <a href="#generator-api-random-double-replacement" id="generator-api-random-double-replacement"></a>

In this example replacement for the Random Double generator, the generator is configured to produce numbers between 2.5 and 10.75.

```json
{
  "name": "number-column",
  "schema": "public",
  "table": "test",
  "links": [
    {
      "schema": "public",
      "table": "test",
      "column": "number-column",
      "metadata": {
        "presetId": "RandomDoubleGenerator",
        "generatorId": "RandomDoubleGenerator",
        "min": 2.5,
        "max": 10.75
      }
    }
  ]
}
```
