Notes: |
The Casio fx-501p and Casio fx-502p were identical calculators except
for the number of available program memory. The Casio fx-502p is
the non-alphanumeric predecessor of the Casio fx-602p.
I've never actually used this calculator. I got it by exchanging
it with a Casio fx-601p I owned with someone who preferred
alphanumeric above memory.
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. |
