This function varies the input numeric value, based on the percentage specified as an extra parameter.
This function applies only to numeric data types: Integer, Long, Float and Double.
| Option | Description |
|---|---|
| Extra parameter |
This function requires an extra parameter.
The extra parameter must be a number, this parameter represents a percentage of modification. The function modifies the input data by multiplying it by a number between the parameter and its opposite. For example, if the input is 100 and the parameter is 10, then the generated value will be a randomly selected value between 90 (100 - 10%) and 110 (100 + 10%). If the extra parameter is 0, it will be replaced with 10. If the input is null, then the function will return 0. |
In the following example, the masked value has been randomly selected between 5 (10 - 50%) and 15 (10 + 50%).
| Input value | Extra parameter | Example of a masked value |
|---|---|---|
| 10 | "50" | 7 |
