Cousin to the CASIO fx-100C. The manual of
this calculator handles both of them. It is also very much similar to
the CASIO fx-85N which lacks the BASE-n functions.
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 the aforementioned 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. |
