Nice 10-digit scientific calculator with a fluorescent display.
Present are the usual bunch of scientific functions but also a
fraction key. A slider is used to switch calculator modes such as
the angle mode and to enable statistical functions. Basically this
calculator is the 10-digit version of the Casio fx-39.
The calculator shows 10 digits normally and 8 digits when scientific notation is used. 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. Thank you, Joop Berck, for donating this nice calculator to the museum. |
