BooleanFunction (The Adobe Experience Manager SDK 2022.11.9850.20221116T162329Z-220900)

java.lang.Object
- org.apache.poi.ss.formula.functions.BooleanFunction

All Implemented Interfaces:

Function
```
public abstract class BooleanFunction
extends java.lang.Object
implements Function
```
Here are the general rules concerning Boolean functions:
1. Blanks are ignored (not either true or false)
2. Strings are ignored if part of an area ref or cell ref, otherwise they must be 'true' or 'false'
3. Numbers: 0 is false. Any other number is TRUE
4. Areas: *all* cells in area are evaluated according to the above rules

    Specified by:
    
    evaluate in interface Function
    
    Parameters:
    
    args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
    
    srcRow - row index of the cell containing the formula under evaluation
    
    srcCol - column index of the cell containing the formula under evaluation
    
    Returns:
    
    The evaluated result, possibly an ErrorEval, never null. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to Double.NaN be sure to translate the result to ErrorEval.NUM_ERROR.
