Get Array Data
Obtain specific information from a variable containing a string of items (an "array"). You can choose to obtain the following types of information:
-
The value of a specific item in the array
-
The total number of items in the array
-
The result of a mathematical calculation performed on the array:
-
Average
-
Maximum Value
-
Minimum Value
-
Sum
-
In order for this command to work properly, all the items in the variable must be delimited (i.e., separated) in a consistent way.
-
Enter the name of the variable from which you want to obtain data
-
Enter the delimiter or the characters that appear before and after each item in the array
-
Choose the type of data you want to obtain. For a mathematical calculation, select the operation.
-
Enter the name of the variable into which you'd like to place the data obtained
-
Instruct the wizard how to handle any errors encountered. Read more about error handling.
In order to perform a mathematical calculation, all values in the array must be numeric. If one or more of the values in the array is non-numeric, the wizard will return an empty result in the variable you have specified. (Note that numbers including currency symbols are treated as non-numeric.)
You can use the Check Type command to validate that variable values are numeric prior to using them in mathematical calculations.
Example
Let's say you run an e-commerce internet website. At the end of each day, you read the amounts of all the day's orders into a variable called daily orders. You'd like to extract the following information: (1) total number of orders; (2) average order amount; and (3) largest order amount.
daily orders = 65.00; 189.95; 645.76; 39.05; 254.36; 98.89; 369.56
Result: number of orders = 7
Result: average order = 237.51
Result: largest order = 645.76
