Aggregates / max

max(dataset, column OR number, number...)

Finds and returns the maximum value in the given column of the given dataset, or the max value in a series of numbers specified as arguments. When looking up the max in a dataset, the column may be specified as an index or as a column name. Any null values in the column are ignored. If there are no rows in the dataset, zero is returned.

For example, suppose you had a table with this dataset in it:

max({Root Container.Table.data}, 1)

... would return 380

You can also use this function to find the maximum in fixed series of numbers, specified as arguments, like this:

max(0, 10/2, 3.14)

... would return 5.

The following example is a great way to make sure a value never goes below zero:

max({SomeValue}, 0}
