. It was introduced in 2003 as the successor to the
HP 32SII,
and discontinued on the introduction of its successor the
HP 35s in 2007.
Features
Its main features are:
*
RPN or traditional semi-algebraic (infix data/algebraic operator entry/postfix one-number function entry), user-selectable
* Two-line LCD display
* Full scientific/engineering mathematical features
*
Keystroke-programmable with full
boolean
Any kind of logic, function, expression, or theory based on the work of George Boole is considered Boolean.
Related to this, "Boolean" may refer to:
* Boolean data type, a form of data with only two possible values (usually "true" and "false" ...
and program-control command sets and line edit, insert and delete
* HP "equation list" equation editor (fully algebraic) in both the stand-alone list as well as in keystroke programs
* HP Solver feature (solves equations and functions for one unknown)
* Function
integration
Integration may refer to:
Biology
*Multisensory integration
*Path integration
* Pre-integration complex, viral genetic material used to insert a viral genome into a host genome
*DNA integration, by means of site-specific recombinase technology, ...
feature
* All mathematical operations and features fully functional in all modes
* Unit conversion and constants
* 31
KB of
random-access user memory (equivalent to about 7 KB on earlier HP programmable models)
The main differences from the HP 32SII are:
* A radical difference in keypad layout and appearance
* Memory is expanded from 2 KB to 32 KB
* Faster processor
* More functions
* Algebraic entry mode as well as RPN
* The display has two lines
* The length of an equation was now restricted to 255 characters (no arbitrary limit in the 32SII)

-styled keypad has been regarded by reviewers as bizarre and difficult to use compared to other HP professional calculators.
Revisions
The 33s went through numerous revisions that have solved two of the most pervasive issues people had with the early models (namely poor screen quality and bad keypad responsiveness).
