        term:         One or more numbers or mathematical terms (separated by separator).
                      Numbers can be positive or negative, fractional or integer.

        separator:    Separator between calculations.
                      Defaults to CRLF (standard Windows linefeed).
        flags:        (bit field)
                  1 = Formats the returned number acc. to system defaults
                      (thousand separators, decimal digits).
                  2 = Formats the returned number with X decimal digits (where X 
                      is specified in the "precision" argument) and no thousand 
                      separators. The format is independent of regional settings.
        precision:    Number of digits after the decimal point in the returned number.
                      Defaults to 2.
