Hewlett-Packard HP-32SII
It took nearly two months for BID.COM to deliver my order, but finally I have an HP-32SII in my hands. This interesting (and, I should add, very good) calculator is an improved version of the HP-32S. To the already impressive capabilities of the HP-32S, this machine adds fractions support, and support for algebraic expressions. It also has two shift keys, simplifying menus at the expense of a more cluttered keyboard.
Like the HP-32S, the HP-32SII has a built-in extended factorial function that calculates the factorial for any real argument. So writing a Gamma function program, my favorite programming example, makes little sense. I've written an implementation of the complex Gamma function for the HP-32S, but rather than repeating it here, here's something new. Just today, I received an e-mail from a fellow calculator enthusiast, who forwarded me some remarkable algorithms from one of the numerous Russian books dedicated to the most successful Russian programmable calculator, the B3-34. Since the B3-34 is an RPN calculator that works much like a typical HP machine, adapting the algorithm to the HP-32SII was a fairly trivial exercise. So here it is, a program that actually calculates the complex logarithm of the Gamma function for any complex argument. To use the program, just enter the imaginary part, hit ENTER, enter the real part, and hit XEQ I. Make sure the calculator is in radians mode, otherwise the result will not be correct.
This program is not as accurate as the one I wrote for the HP-32S, but it sure requires a lot less program space, even though I haven't even optimized it yet, making use of capabilities in the HP-32SII not present in the Russian models, such as register recall arithmetic.
