HP-32SII Scientific RPN Calculator
Entry mode RPN


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.
