DMath: RAND(A)
Creates a random and equal distribution of values between 0 and A
Purpose
Use this function to:
- Create evenly distributed Random data
Return Value
Property | Value |
---|---|
FieldType | Double |
FieldSize | Low / Med / High / Continuous |
DataType | Discrete / Continuous |
DataSize | Short / Integer / LongInteger / Double |
Example Return Value: X*.XXXXXX....-X*.XXXXX
e.g. 21.000000, 98754654.123456, -5.000000, -654.320000
Parameters
Parameter | JSON | Description |
---|---|---|
Table | “targetTable”: “MyTableName” | The target table on which the new field will be created |
Filter | “dataset”: {DataSet_JSON} | Optional. If a filter is applied, records not in the filter recordset will be returned as null. |
Math Function | “p1”: “RAND(A)” | RAND(A) |
A | “p2”: “NumericFieldName” “p2”: “#N*.N*” | Required. Numeric input for Maximum/Minimum value of created data. If A is less than 0, negative values will be created. If A is greater than 0, positive values will be created. Only integer values are returned - If A = 1, then RAND(A) will have a distribution between 0 and 1. Supports:
|
Treat Null as Zero | "nullIsZero": true "nullIsZero": false | True/False. Default = False If true, then any null values in the input fields will be treated as if they have a value of 0. |
