The calculator has rubber buttons that have an excellent feel. The whole look of the calculator is clean and neat in my opinion.
The ► key acts as a backspace key when entering numbers.
Next to the normal memory function this calculator also has 6 distinct memories accessable using Kin and Kout. They are also used for statistical operations, and K1...K6 are used to store statistical sums.
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 exponent, otherwise it will enter the constant π.
Function wise the same as the CASIO fx-85N which also has a backup battery.
