Description

Brand:	CASIO
Model:	fx-115N
Type:	Scientific calculator
Picture:
Batteries:	Colar cell & GR927 x 1 (CASIO C-POWER system)
Lifetime:	Introduced: 1995 Terminated: unknown
Notes:	Cousin to the CASIO fx-100C. The manual of this calculator handles both of them. This 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. It has ten-digit accuracy and is capable of statistics and BASE-n conversions and calculations. 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. Many thanks to Richard Pilkington of the University of Salford for donating this calculator to the museum.
