ImReal (Keikai Spreadsheet Build 6.0.0 API)

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

All Implemented Interfaces:

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

Returns the real coefficient of a complex number in x + yi or x + yj text format.
Inumber A complex number for which you want the real coefficient.
Remarks
- If inumber is not in the form x + yi or x + yj, this function returns the #NUM! error value.
- Use COMPLEX to convert real and imaginary coefficients into a complex number.

public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex,
                          ValueEval inumberVE)

    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).
