IndexAnd (FPScript)
Performs a Boolean AND operation for two index data sets.
Syntax
IndexAnd(Index1, Index2)
The syntax of the IndexAnd function consists of the following parts:
Part |
Description |
|---|---|
Index1 |
The first index data set with ascending indices or 2D indices. Permitted data structures are data series und data matrix. All real data types are permitted. |
Index2 |
The second index data set with ascending indices or 2D indices. Permitted data structures are data series und data matrix. All real data types are permitted. |
Remarks
As the result the function returns a data series of data type 64-bit integer.
Before the Boolean operation, the data are converted into 64-bit integers, if applicable. The two data series to be combined must contain values greater than or equal to zero which are sorted in ascending order. The result is a data series or data matrix containing all of the indices that occur in Index1 and Index2. The result therefore contains the intersection of both data sets.
If the argument is a list, then the function is executed for each element of the list and the result is also a list.
