   $SYNTAX$
      ft_Round( <nNumber> [, <nRoundToAmount>           ;
                [, <cRoundType>  [, <cRoundDirection>   ;
                [, <nAcceptableError> ] ] ] ] )            -> nNumber
   $ARGUMENTS$
      <nNumber> is the number to round

      <nRoundToAmount> is the fraction to round to or the number of places,
      default is 2.

      <cRoundType> is the type of rounding desired

         "D" for Decimal       (3 for thousandth, 1/1000)  (default)
         "F" for Fraction      (3 for thirds, 1/3)
         "W" for Whole numbers (3 for thousand, 1000)

      <cRoundDirection> is the direction to round the number toward

         "U" to round Up      1.31 ->  1.4
                             -1.31 -> -1.4
         "D" to round Down    1.36 ->  1.3
                             -1.36 -> -1.3
         "N" to round Normal  1.5  ->  2
                             -1.5  -> -2
                              1.49 ->  1
                             -1.49 -> -1

      <nAcceptableError> is the amount that is considered acceptable
      to be within, i.e., if you're within this amount of the number
      you don't need to round
   $RETURNS$
      The number, rounded as specified.
   $DESCRIPTION$
      This function will allow you to round a number.  The following can
      be specified:
        a. Direction (up, down or normal - normal is 4/5 convention)
        b. Type (whole, decimal, fraction)
        c. Amount (100's, 5 decimals, 16th, etc.)
   $EXAMPLES$
      // round normal to 2 decimal places
      ? ft_Round( nDollars )

      // round normal to 6 decimal places
      ? ft_Round( nIntRate, 6 )

      // round to nearest thousands
      ? ft_Round( nPrice, 3, NEAREST_WHOLE_NUMBER )

      // round Up to nearest third
      ? ft_Round( nAmount, 3, NEAREST_FRACTION, ROUND_UP )

      // round down to 3 decimals Within .005
      ? ft_Round( nAvg, 3, , ROUND_DOWN, .005 )
