0000000668 00000 n According to HP, the calculator has been engineered for heavy-duty professional use, and has been tested under extreme environmental conditions. Useful to insert a single REGX, Y, Z or T instruction for a RCL stack register step. The ABS function will return a vector's magnitude. Since the content of an equation is not validated unless and until it gets processed, it may contain any sequence of characters, including text strings. Since an equation can contain any sequence of characters, it may be composed as a message to be displayed. Like most HP calculators, it defaults to RPN. 0 The 26 alpha-labelled variables and the six statistics registers are permanently allocated; the rest of the memory space can be occupied by up to 801 more variables which can only be accessed indirectly. [9] Inverse and hyperbolic trigonometry functions cannot be used with complex numbers. In non-decimal bases, the word length is fixed at 36 bits, and uses two's complement negation. Instead of selecting an equation from a list, the user presses FN=, then the program's label, and either SOLVE or ∫, which prompts for the name of the target variable. There are also two built-in entries in the equations list, to allow solving all variables in a system of linear equations. A cross-product function is not available, nor any function to extract individual elements from a vector, but these can be readily calculated by the user. %PDF-1.4 %���� The stack levels are named X (the bottom), Y, Z, and T (the top); they have no connection with the variables of the same names. Indirect access to any variable is achieved by storing its sequence number (0 upwards) in the I or J variable as a pointer and then accessing the variable via (I) or (J). The symbol √ is called the radical sign or radix. endstream endobj 233 0 obj <>/Outlines 37 0 R/Metadata 47 0 R/PieceInfo<>>>/Pages 46 0 R/PageLayout/OneColumn/OCProperties<>/OCGs[234 0 R]>>/StructTreeRoot 49 0 R/Type/Catalog/LastModified(D:20070527163215)/PageLabels 44 0 R>> endobj 234 0 obj <. The expression can be edited using the arrow and backspace keys, and re-evaluated as desired. 0000100578 00000 n No arbitrary limit to length of equations (the 33s had a limit of 255 characters). It is entered by the user starting with a square bracket [, then the element values separated by commas ,. The faceplate is metal, bonded to the plastic case. The HP 33s had only label addressing. All programs are stored in one continuous program space, and may be created and edited by switching to programming mode, using the PRGM key. HP have published program code for the 35s which enables this.[17]. [5][2][12] While welcoming the improved handling of complex numbers compared to the 33s, the incomplete support for them has been criticised. Regardless of which display base is set, non-decimal numbers must be entered with a suffix indicating their base, which involves three or more extra keystrokes.[2]. [6] This was previously only available to teachers for classroom demonstration purposes. Complex numbers can be entered in either rectangular form (using the i key) or polar form (using the Θ key), and displayed in either form regardless of how they were entered. The HP 35s (F2215A) is a Hewlett-Packard non-graphing programmable scientific calculator. The key to this is the RPN memory stack, in which the … %%EOF Re: HP-35s tip: Stack review in RPN Message #7 Posted by Gene Wright on 20 Sept 2007, 12:23 p.m., in response to message #5 by Meenzer. The calculator's settings include a numbered flag which specifies whether equations in programs are to be evaluated or displayed at run time. In contrast to the usual computer-science terminology, RPN calculators such as this refer to the operational end of the stack as the bottom and the far end as the top. The calculator provides a set of 41 mathematical and physical constants, which may be scrolled through and selected using the CONST key. The maximum denominator may be specified using the /c function. The 35s's statistics capabilities are fairly standard. 0000002730 00000 n Each stack level can contain any of the data types supported by the machine: real number, complex number, or vector. The calculator may be set to automatically display values as mixed fractions by toggling the FDISP key. The calculator is entirely self-contained; there is no facility for upgrading the firmware, nor for loading/saving programs and data. [2][5], Response to the calculator's logic has been mixed. There are no functions for extracting real and imaginary parts, though that can be worked around, using the formulas Re = r cos Θ and Im = r sin Θ. "Equations" in this context means expressions ( f(x,...) ), equalities ( f1(x,...) = f2(x,...) ), and assignments (y = f(x,...)), which are each handled in different ways. It is conventional to use each label to mark the start of a separate program, so that any program may be executed by a command in the form XEQA. The increase in addressable registers and introduction of program line-number addressing have been seen as a big improvement over the 33s.
