  /*
  The second parameter is the number of decimal places that the number should have. 
  If the number contains more decimal places than required it will be rounded to the nearest number with that number of decimal places. 
  If it has fewer decimal places than specified zeroes will be added to the end.
  The third parameter is the thousands separator. 
  The fourth parameter is the decimal point. Either a period or comma is normal here.
  The fifth and sixth parameters are used for monetary values and one or other of them will contain the currency symbol when required. 
  If your location uses a currency symbol hard against the left of numbers then place that symbol by itself in the fifth parameter eg. '$'. 
  If you normally have a space after the currency symbol then add it after the symbol in this '$ '. 
  If your currency symbol comes after the amount instead of before then place it in the sixth parameter instead of the fifth parameter.
  The seventh and eighth parameters define the symbols to place around the number when the value is negative. 
  The usual values for these parameters would be '-','' but you may have a situation where you want to use '(',')' or even '',' CR'.
