Difference is a mathematical function that returns the absolute value of the difference of a numeric value, row, or column subtracted from another numeric value, row, or column. This is also known as the variance. The function syntax:
Difference(arg1, arg2)
where arg2 is subtracted from arg1 and are one or more of the following arguments:
Argument | Description |
---|---|
numeric | A numeric value. For example, Difference (3, 5) returns the absolute value 2. Numeric values can include decimals and negative values. |
row, column, or reference | A pointer to a row, column, or cell within a grid. References can be specified in several ways. The reference syntax: GridName.GridElement[segment(range)].Property The following example returns the difference of two rows in form grid1: Difference( grid1.row[1], grid1.row[6] ) |
function | An embedded function |
Note: | The Difference function returns the absolute value of arg2 subtracted from arg1, whereas the minus sign in subtraction negates a number. |
Examples:
The following example returns the absolute value of 8:
Difference(3, -5)
The following example calculates the difference of two aggregate columns:
Difference( column[E], column[G] )
Note: | You can type the text label “Difference” or “Variance.” |
