The HP-32S was a programmable RPN Scientific Calculator introduced by Hewlett-Packard in 1988. A model was built in 1987 by HEWLETT-PACKARD COMPANY in USA (sérial number 2838A13810) and discontinued in 1991. It continued the tradition of the HP-15C programmable RPN Scientific Calculator. But some functions of the HP-15C were omitted (matrix calculations) and some were reduced in functionality (complex calculations), so to some extent it's more correct to say that the HP-32S rather expanded on the HP-34C. It supported complex math, statistics, probability, etc.

The HP-32SII added algebraic math, fractions and a second shift key. This was introduced in 1991 and discontinued in 2002.
Sample Program
; This is an HP-32Sii version of the Euclidean algorithm ; to find the greatest common divisor (GCD). ; You run this by putting the two numbers for ; which you want to find the GCD and pressing "XEQ E" E01 LBL E E02 STO A F01 LBL F F02 ÷ F03 FP F04 RCL A F05 x F06 1 F07 x>y?

gollark: Idea: optimized matrix fibonaccization using AVX.
gollark: OH WAIT, I CAN, I didn't not unexpect this.
gollark: I can't say I didn't not unexpect this.
gollark: Is Macron just SUBLEQ now?
gollark: Well, the matrix way lets you get fib(n) in O(log n) time, thus good.
