Here is another programmable financial calculator from Casio.

Like its bigger cousin, the FC-1000, the FC-200 also has a somewhat gutted program model, presumably to make room for the financial functions. This calculator, too, lacks essential capability such as trigonometric functions.

My favorite programming example, the Gamma function, using this calculator, can be implemented very accurately on the FC-200. As the Gamma function forms the basis of many statistical computations, so a reliable implementation must be of value on a calculator aimed at the business/financial market:
