# MAX

The MAX function calculates the larger value of two expressions.

Return Value

DECIMAL

Syntax

MAX(expression1, expression2)

Arguments

expression1

  One expression to be compared.

expression2

  The other expression to be compared.

Notes

Dimensions of the Result Returned by MAX

Ordinarily, the dimensions of both the expressions you want to compare and the results of MAX are the same. When the dimensions of one expression are a subset of the other's dimensions, then the results of MAX are dimensioned by the larger set of dimensions. In any case, the results of MAX are dimensioned by the union of the dimensions of the two expressions.

Examples

Example 16-57 Calculating Whether Actual or Budget Values Are Larger

Suppose, for each of the first six months of 1996, you want to find whether the `actual` value or the `budget` value is larger for the line item Cost of Goods Sold (Cogs) in the `Sporting` division.

    LIMIT line TO 'Cogs'
    LIMIT division TO 'Sporting'
    LIMIT month TO 'Jan96' TO 'Jun96'
    REPORT DOWN month actual budget MAX(actual budget)

The preceding statements produce the following output.

    DIVISION: SPORTING
                   --------------LINE--------------
                   --------------COGS--------------
