Constructs this object from the raw data

Parameters:

t - the basic number formula record

fr - the formatting records

es - the external sheet

nt - the name table

nf - flag indicating whether the 1904 date system is in use

si - the sheet

Gets the formula as an excel string

}

Gets the raw bytes for the formula. This will include the parsed tokens array. Used when copying spreadsheets

 public NumberFormat getNumberFormat()

Dummy implementation in order to adhere to the NumberCell interface

 public CellType getType() 
{
    return CellType.DATE_FORMULA;
}

Returns the cell type

 public double getValue() 
{
    return 0;
}

Interface method which returns the value
