EC-449  (650-0925)            Features                Faxback Doc. # 6463

The EC-449 Scientific Calculator uses the latest in scientific technology
making it one of the most complete and compact calculators available.  It
can help you solve problems in anything from the basic functions of
addition, subtraction, multiplication, and division to the more complex
functions of trigonometry, hyperbolics, logarithms, or statistics.  You
can enter mathematic operations using up to 18 parentheses at six levels.
Then using algebraic logic, the calculator automatically determines which
mathematic operation to perform first.  Its specially designed 8-digit
liquid-crystal display is easy to read in changing or poor lighting
conditions.  The handy size lets you carry it wherever you go.

Its features include:

            Algebraic Operation - Lets you enter calculations exactly as
                                  they are written.

           Full-Feature Display - Displays an eight-digit mantissa with
                                  sign and a two-digit exponent with
                                  sign.

Extra Wide Range of Calculation - Allows calculations within the range
                                  of 10 to the power of 99 to 10 to the
                                  power of -99.

           Conversion Functions - Helps you convert fractions to
                                  decimals; degrees/hours, minutes, and
                                  seconds to decimal format and back; and
                                  polar-to-rectangular and rectangular-
                                  to-polar coordinates.

           Trigonometric and
           Hyperbolic Functions - Performs trigonometric and hyperbolic
                                  functions using degree, radian, or
                                  gradient as the basic unit.

          Logarithmic Functions - Provides quick access to log base- 10
                                  and natural logarithm (base-e).

          Statistical Functions - Lets you calculate arithmetic mean,
                                  sample and population standard
                                  deviations, and sum of values.

Independent Accumulating Memory - Lets you temporarily store, add to,
                                  and subtract from your calculations.

           Rugged Plastic Case - Helps protect the calculator from rough
                                  handling.
