Bin2Dec (Keikai Spreadsheet Build 6.0.0 API)

java.lang.Object
- org.apache.poi.ss.formula.functions.Fixed1ArgFunction
- - org.apache.poi.ss.formula.functions.Bin2Dec

All Implemented Interfaces:

FreeRefFunction, Function, Function1Arg
```
public class Bin2Dec
extends Fixed1ArgFunction
implements FreeRefFunction
```
Implementation for Excel Bin2Dec() function.
Syntax:
Bin2Dec (number)

Converts a binary number to decimal.
Number is the binary number you want to convert. Number cannot contain more than 10 characters (10 bits). The most significant bit of number is the sign bit. The remaining 9 bits are magnitude bits. Negative numbers are represented using two's-complement notation.
Remark If number is not a valid binary number, or if number contains more than 10 characters (10 bits), BIN2DEC returns the #NUM! error value.

public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex,
                          ValueEval numberVE)
```
    Description copied from interface: Function1Arg
    
    see Function.evaluate(ValueEval[], int, int)
    
    Specified by:
    
    evaluate in interface Function1Arg
  - evaluate
```
public ValueEval evaluate(ValueEval[] args,
                          OperationEvaluationContext ec)
```
    Specified by:
    
    evaluate in interface FreeRefFunction
    
    Parameters:
    
    args - the pre-evaluated arguments for this function. args is never null, nor are any of its elements.
    
    ec - primarily used to identify the source cell containing the formula being evaluated. may also be used to dynamically create reference evals.
    
    Returns:
    
    never null. Possibly an instance of ErrorEval in the case of a specified Excel error (Exceptions are never thrown to represent Excel errors).
