| 3 | The average function calculates the middle number of a set of numbers by adding them all together and then dividing by how many numbers there are. | ||
| 4 | |||
| 5 | == Syntax : == | ||
| 6 | |||
| 7 | * **${ixf:avg(xpathExp1, xpathExp2)}** calculates the average of the results obtained from evaluating "xpathExp1" and "xpathExp2". | ||
| 8 | * **${ixf:avg(xpathExp, "10")}** the outcome will be the sum of the value resulting from evaluating "xpathExp" and the number 10 dividing by 2. | ||
| 9 | * **${ixf:avg("10","12","100")}** the result will be 40,66, which is the sum of 10, 12 and 100 dividing by 3. | ||
| 10 | |||
| 11 | Ensure that numerical values are between double quotes : ${ixf:avg("10","12","100")}, | ||
| 12 | |||
| 13 | while xpath expressions should remain without any quote enclosures. | ||
| 14 | |||
| 15 | |||
| 16 | == Example : == | ||
| 17 | |||
| 18 | * **${ixf:avg(Documents/Order/DeliveryAddress/OrderLine/Price,"10"}** | ||
| 19 | |||
| 20 | Let's suppose that the result obtained from evaluating //Documents/Order/DeliveryAddress/OrderLine/Price// is 30, so the average is 20.00. | ||
| 21 | |||
| 22 | == Note: == | ||
| 23 | |||
| 24 | * Numerical values can be also enclosed within //single quotes// : ${ixf:avg('10','12','100')} **OR **//mix single and double quotes//, like this: ${ixf:avg("10",'12','100')}. | ||
| 25 | * The default display for the average includes **two** decimal places. |
