  		• In Excel 2007 (and later) this function has been removed from the Analysis ToolPak add-in and is available as standard.
     
  		• In Excel 2003 this function is only available when you have the Analysis ToolPak add-in loaded.
     
  		• If "inumber" is not in the form of x + yi or x + yj, then #NUM! is returned.
     
  		• You can use the COMPLEX() function to convert real and imaginary coefficients into a complex number.
