Examples
For example, suppose you had a table with this dataset in it:
ProductCode | Quantity | Weight |
---|---|---|
BAN_002 | 380 | 3.243 |
BAN_010 | 120 | 9.928 |
APL_000 | 125 | 1.287 |
FWL_220 | 322 | 7.889 |
min({Root Container.Table.data}, 1) //... would return 120
min(0, 10/2, 3.14) //... would return 0
min({SomeValue}, 180) //This example is a great way to make sure a value never goes above 180
