Casio OH-7000G
The Casio OH-7000G is an overhead projector version of Casio's classic graphing calculator, the fx-7000G. Apart from a difference in house styling and, of course, the see-through, temperature resistant LCD display, the OH-7000G is identical to the fx-7000G.
Demonstrating this calculator's programming model is the example below that computes the logarithm of the Gamma function to a high degree of accuracy using the Lanczos-approximation.
