Name | If (Double) |
Syntax | If (Boolean condition, Real thenValue, Real elseValue) |
Purpose | To evaluate a given condition and if true, return result of thenValue. Otherwise, to return the result of elseValue. |
Description | Returns the value of ‘Then’ expression or ‘Else’ expression depending on the value of condition. |
Return Type | Double |
Parameters | Condition [System.Boolean] – Condition that is evaluated thenValue [System.Double] – This Parameter’s value is returned if the result of ‘condition’ parameter is true. elseValue [System.Double] - This Parameter’s value is returned if the result of ‘condition’ parameter is false. |
We have a Customers dataset which we will use to evaluate and transform the Items field.
In this example we will use the Expression object to define the condition, and a Variables object to define a real thenValue and a real elseValue.
Where,
Condition: Items = “1”
thenValue = 1.23
elseValue = 2.23
In the output, you can see that real values, 1.23 and 2.23, have been returned depending on whether the Items field condition was met.
