Differences Between HP 32S and HP 32SII
The HP 32S and HP 32SII are two classic RPN calculators which feature a rich set of scientific calculations, including logarithms, trigonometry, hyperbolic functions, integer part, fraction part, absolute value, statistics, and linear regression (y = mx + b). Both are keystroke RPN programming programs with a capacity of 390 bytes.
What are the differences?
HP 32S
* Production: 1988 - 1991
* Keyboard Colors: dark brown, almost black keys; one orange shift key
* One key deals with scrolling: down, with up shifting
HP 32SII
* Production: 1991 - 2002
* Keyboard Colors: dark brown keys, orange shift key, blue shift key (1st edition); black keys, green shift key, pink shift key
* One key deals with scrolling: down, with up shifting
* Has four sets of US/SI conversions: kg/lb, °C/°F, cm/in, l/gal
* Pressing the decimal key ( [ . ] ) twice will create fractions and mixed fractions. The FDISP toggles between decimal approximation and fractions.
