fx180pa.jpg (30711 bytes)The Casio fx-180Pa is an upgraded version of Casio's successful entry-level programmable calculator, the fx-180P. The two calculators are similar in appearance and functionality; the only significant difference is that the fx-180Pa offers the ability to perform number base calculations in base 2, 8, and 16.

The two calculators have an essentially identical programming model, which is demonstrated by the program below, which computes the logarithm of the Gamma function:

K2=2.5066284644
K3=41.41740453
K4=-27.063892494
K5=2.2393179633
K6=1.15
