Hewlett-Packard Company Palo Alto, CA 94304 USA Introduction Congratulations! Whether you are new to HP calculators or an experienced user, you will find the HP-15C a powerful and valuable calculating tool. The HP-15C provides: 448 bytes of program memory (one or two bytes per instruction) and sophisticated programming capability, including conditional and unconditional branching, subroutines, flags, and editing. Four advanced mathematics capabilities: complex number calculations, matrix calculations, solving for roots, and numerical integration. Direct and indirect storage in up to 67 registers. This handbook is written for you, regardless of your level of expertise. The beginning part covers all the basic functions of the HP-15C and how to use them. The second part covers programming and is broken down into three subsections – The Mechanics, Examples, and Further Information – in order to make it easy for users with varying backgrounds to find the information they need. The last part describes the four advanced mathematics capabilities. Before starting these sections, you may want to gain some operating and programming experience on the HP-15C by working through the introductory material, The HP-15C: A Problem Solver, on page 12. The various appendices describe additional details of calculator operation, as well as warranty and service information. The Function Summary and Index and the Programming Summary and Index at the back of this manual can be used for quick reference to each function key and as a handy page reference to more comprehensive information inside the manual. Also available from Hewlett-Packard is the HP-15C Advanced Functions Handbook, which provides applications and technical descriptions for the root-solving, integration, complex number, and matrix functions. Note: You certainly do not need to read every part of the manual before delving into the HP-15C Advanced Functions if you are already familiar with HP calculators. The use of _ and f requires a knowledge of HP-15C programming. 3 Contents The HP-15C: A Problem Solver .................................... 12 A Quick Look at v

  • RPN Calculators for Linux
    LinuxFocus article number 319 http://linuxfocus.org RPN calculators for Linux by Guido Socher (homepage) About the author: Abstract: My first RPN calculator was a HP15c and it was RPN stands for Reverse Polish Notation. Reverse Polish Notation was love at first sight. developed in 1920 by Jan Lukasiewicz as a way to write a mathematical expression without using parentheses and brackets. It takes a few minutes to learn RPN but you will soon see that this entry method is superior to the algbraic format. _________________ _________________ _________________ Introduction RPN pocket calculators became popolar with the HP calculators. HP used this entry method already for it's first calculator in 1968. If you search the internet you will find that there is a whole fan club behind those HP calculators. I have made a number of very good links available at the end of this article. Most of those HP calculators are today collectors items and sell now for much more than their original price. In this article will present some of the RPN desktop calculators available for Linux. We will not only look at the HP emulators which are available but also other RPN calculators which are totally independent of HP. What is RPN? Why RPN? RPN calculators use a stack and all mathematical operations are executed immediately on the lower level of the stack. The stack is used as a memory to save results which you need to further evaluate your formula. Therefore you do not need any brackets on an RPN calculator. You first enter the numbers, push them up the stack, and then you say what you want to do with those numbers.

  • Rplsh: an Interactive Shell for Stack-Based Numerical Computation
    RPLsh: An Interactive Shell for Stack-based Numerical Computation Kevin P. Rauch Dept. of Astronomy, University of Maryland, College Park, MD 20742 Abstract. RPL shell1, or RPLsh, is an interactive numerical shell designed to combine the convenience of a hand-held calculator with the computa- tional power and advanced numerical functionality of a workstation. The user interface is modeled after stack-based scientific calculators such as those made by Hewlett-Packard (RPL2 is the name of the Forth-like pro- gramming language used in the HP 48 series), but includes many features not found in hand-held devices, such as a multi-threaded kernel with job control, integrated extended precision arithmetic, a large library of spe- cial functions, and a dynamic, resizable window display. As a native C/C++ application, it is over 1000 times faster than HP 48 emulators (e.g., Emu483) in simple benchmarks; for extended precision numerical analysis, its performance can exceed that of Mathematica R by similar amounts. Current development focuses on interactive user functionality, with comprehensive programming/debugging support to follow. 1. Introduction The notion of progress in computer hardware has always been closely tied to the speed and sophistication with which numerical calculations can be performed. While the continuation of Moore's Law has resulted in hand-held devices more powerful than the 30 ton ENIAC machine, there is a growing gap between the speed and capabilities of hand-held scientific calculators as compared to desk- top workstations|the result of both market forces (pricing pressure) and phys- ical limitations (keyboard/screen size). Numerical analysis packages such as Mathematica or IDL, by contrast, are oriented towards script or command line processing, and lack the interactive amenities found in a traditional calculator.

  • HP-45 Owner's Handbook
    Hewlett-Packard's interest in computation evolved as a natural extension of our traditional involvement in measurement problem solving. At an early date, HP recognized the growing need for a family of computational products designed to work easily and effectively with scientific instruments. In 1966 we introduced the first digital minicomputer specifically designed to meet this need. Soon after, we followed up with our first programmable calculator. From these beginnings, HP has now become an acknowledged leader in the field of computational problem solving. More than 20,000 HP programmable calculators and digital computers are at work in a wide range of applications in science, industry, education, medicine, and business. Their ef­ fectiveness is further enhanced by a complete line of accessory devices, ranging from digital tape and disc drives to card and tape readers, printers, and plotters. Lately we've coupled our experience in scientific problem solving and computational technology to bring you new dimensions in personal computation-the HP-80 Business Pocket Calculator for solving problems in business and finance, the HP-35 Scientific Pocket Calculator for engineering/ scientific applications, and now the HP-45 Advanced Scientific Pocket Calculator whose expanded functional capability and multiple storage registers allow complex problems to be handled with unprecedented ease. <CI HEWLETT· PACKARD COMP"NY, 1973 Attention Please! To give you more computing power, your HP-45 works in a con­ sistent and natural way that may be slightly different from previous calculators you have operated. Even though your new HP-45 is simple to operate, and you can start solving problems immediately by following the Quick Reference Guide accompanying the HP-45, you will find it worthwhile to read this handbook.

  • RPN Calculates Faster. Get Accurate Results in Less Time with the HP 12C
    RPN calculates faster. Get accurate results in less time with the HP 12c. WHAT IS RPN? RPN (Reverse Polish Notation) is a mathematical notation that allows users to solve problems by mimicking how they learned to do math on paper. The operators (+,–,x,÷) are placed after the arguments (for example, 3+4 becomes 3 {ENTER} 4 +) allowing users to stack number sequences and operations, working from the bottom up. RPN eliminates the need for parentheses in complex calculations and reduces keystrokes, making problem solving quicker and more effi cient. T T Pressing an operator key (+ - x ÷) always collapses the bottom two rows of the stack. Z Z Y 3 x Y X 4 + X 7 Solving a Basic TVM Problem PV= 50 What is the Future Value of $50 invested today at r = 3% TVM Formula Formula with inputs N 5 3% interest for 5 years? N = 5 FV = PV x (1 + r) FV = 50 x (1 + .03) FV = ? Traditional Calculation Methods You might think all traditional calculators operate the same way, but there are actually two common operating modes, which require users to input formulas diff erently. Chain Algebraic Mode: Chain Mode calculates from left to right without following the Order of Operations. 50 x (1 + .03^5) = Algebraic Mode: Algebraic Mode follows the Order of Operations (Please Excuse My Dear Aunt Sally). 50 x (1 + .03)^5 = If you’re not sure which mode your calculator uses, you likely add extra parentheses to Mode Unknown: avoid potential errors, making calculations complicated and time consuming. 50 x ((1 + .03)^5)= RPN Method Final Answer: $57.96 RPN breaks equations into simpler components, making them easier to solve.
