Notes: |
The Casio fx-180p is the programmable follow-up on the Casio fx-80 series
design. It uses plain AA batteries and is therefore suitable for intense
usage.
This calculator could store two separate programs. Programs are just key-sequences and can not be edited once entered. It is therefore important to use valid input data even when entering programs, for a program has to be re-entered when an error (invalid operation) occurs during programming. Simple loops were possible using the 'RTN' operation.
It also has a wide range of statistical operations, including
random numbers and two-dimensional functions. 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. When a one-dimensional function is programmed in one of the programs, this calculator can calculate a partial integral of that function as well. This was really nice at school, you could verify the correctness your answer! All in all quite a nice calculator, especially because it looked just like the standard school calculators. |
