CASIO fx-85N


Brand: CASIO
Model: fx-85N
Type: Scientific calculator
Picture: CASIO fx-85N
Batteries: Colar cell & GR927 x 1 (CASIO C-POWER system)
Lifetime: Introduced: 1989
Terminated: unknown
Notes: This scientific calculator runs on solar power, even very dim light is enough to power it (as you can see, the lamp of the scanner was enough to start it). It also has a backup lithium battery to safeguard the calculator’s memory. The calculator runs fine without the battery. It has ten-digit accuracy and is capable of statistics.

The calculator has rubber buttons that have an excellent feel. The whole look of the calculator is clean and neat in my opinion.

This calculator (as do many other CASIO scientific calculators) uses one and the same key for both the constant π as well as exponents. This works as follows. When you first enter digits, the "EXP"-key will enable you to enter the numbers exponent, otherwise it will enter the constant π.

Similar to the CASIO fx-115N which has the same case and has the addition of BASE-n functions.
