hp17bii.jpg (21485 bytes)The HP-17BII is the current successor of the HP-17B, a business calculator made by Hewlett-Packard. Its features are identical to those of the HP-17B, with one significant exception: the HP-17BII reintroduced "RPN" mode as an optional operating mode for this calculator.

Like the HP-17B, the HP-17BII also offers limited programmability in the form of its "SOLVE" feature. With the help of the IF and Σ functions, even simple loops and conditional constructs can be implemented. Here again is my version of the Gamma functionin a form that evaluates correctly for both positive and negative arguments:
