The square root of a number, n, is that value when multiplied by itself equals n. 2 x 2 = 4 and = 2. Calculating the square root of the number is the inverse operation of squaring that number = n. The "√" symbol is called the "radical" symbol or "check mark." MS Word has the radical symbol, √, but we often use it with a line across the top. This is called the "vinculum" circa 12th century. The expression " (2)" is read as "root n", "radical n", or "the square root of n". The vinculum extends over the number to make it inclusive e.g. Most HP calculators have the square root key as a primary key as shown in Fig. 1 because it is used so much. Roots and Powers Numbers may be raised to any power (y, multiplied by itself x times) and the inverse operation, taking the root, may be expressed as shown below.

  • HP Calculator Programming Richard J
    HP Calculator Programming Richard J. Nelson Introduction Do you use an HP calculator that has a programming capability, and do you actually use it? Of the 24 models, see Table 1 below, 23 are on the HP website 13, or 54.2%, are programmable. If the Home and Office machines are omitted, the numbers are: 17 models, and 13 or 76.5%, are programmable. What does this mean? A program is a sequence of instructions (functions and/or data) that are keyed (or loaded) into the calculator’s memory that will solve a particular problem or provide specific information. A program capability also includes special instructions that provide prompting for inputs and labeling for outputs. Another aspect of a program capability is the ability to perform decision logic so the particular parts of a program may be changed depending on the results of previous instructions. This capability provides “intelligence” to the program. The program capability of the 10 current models ranges from very simple such as the HP-12C to very complex (and very powerful) such as the HP 50g. Older HP calculators such as the HP-71B or HP-75C used a computer like programming language called BASIC. The HP-12C and HP-15C programing language is an RPN FOCAL(1) like language, and the HP 50g uses an RPL programming language. The algebraic calculators use what may be called an Aplet programming language.

  • A Hewlett Packard Infrared Signal Decoder
    A Hewlett Packard Infrared Signal Decoder Martin Hepperle June 2015 – November 2017 Several Hewlett Packard pocket calculators are able to send printer output via Infra-Red (IR) signals to a small portable printer. They use an HP-specific transmission protocol which is also called “Red Eye”. This protocol is different from the better known IrDA protocol. This document gives a brief overview of the format and describes hard- and software to build a decoder system for this protocol. This system allows receiving the “Red Eye” signals with a computer via a serial or an USB interface. Printers with IR Interface In 1987 HP introduced the small IR printer 82240A (replaced later by the improved variant 82240B). The ON/OFF switch of the printer shows a red dot when in the ON position and the IR receiver is mounted behind a transparent red window. Therefore protocol has been given the nickname “Red Eye”. HP has long discontinued the production of this printer but even today in 2015 you can still find many dealers offering their stock at relatively high prices. There is also at least one manufacturer who offers similar printers with improved technology but still understanding the “Red Eye” protocol. Several rather expensive measuring systems are still in use in automotive and heating system diagnosis so that there seems to be a market for replacement printers. On the other hand you can find used but working printers on eBay for less than 20€, if you are lucky. Figure 1: The HP 82240B printer with its “Red Eye” on/off, darkness and paper advance controls.

  • Measuring Calculator Current Richard J
    Measuring Calculator Current Richard J. Nelson Introduction The most important measurement of a semiconductor or semiconductor device is its current usage. I once visited an assembly house in Asia that packaged integrated circuits, IC’s, (commonly called chips) into plastic packages. The finished IC’s were then 100% tested using a massive computer controlled very expensive digital signal tester. I noticed that the tester wasn’t in use and I asked why. The test engineer explained that they had found that they could simply measure the quiescent current and they could determine 99.9% of the time that the circuit was working. Besides, the hundreds (and often thousands) of specific digital conditions of the IC functions took much longer by a factor of at least ten. Calculators are semiconductor products and measuring the current that they draw under various usage/mode conditions provides a good indication of what is happening. Pressing “on” with a blank calculator display just doesn’t tell you very much. Current is the most problematic basic electronics measurement – vs. voltage or resistance. Modern digital nultimeters, DMMs, are cheap, accurate, and readily available. All too often, however, you will find that the current range doesn’t work – usually because of a blown internal fuse. Most electrical measurements are made by placing the probes across two points on the component or circuit under test. Measuring current, however, requires that you insert the meter into the circuit. This means that you must cut or un solder the circuit and this is usually not convenient. Current Range An interesting aspect of electronics is the very wide range of values that are involved.

  • Ostrowski's Method for Finding Roots
    Ostrowski’s Method for Finding Roots Namir Shammas Introduction Mathematicians, statisticians, engineers, and scientists frequently deal with problems that require the calculation of one or more roots of functions. When HP launched its first programmable calculator, the HP-65 in 1974, the accompanying Standard Pac included a root-seeking program. The HP-65 Math Pac 1 also included another root-finding program. Over the following years, HP released new programmable calculators; each included root-seeking programs in their standard and math pacs. In 1978, HP launched the HP-34C that contained the very first built-in root-finding Solver. The Solver was a new, powerful, and convenient tool for calculating the roots of single-variable nonlinear equations. The Solver implemented a clever version of the Secant method. This method along with Newton’s method remained the two favorite root-seeking algorithms for many decades among users of programmable HP calculators. In this article I present the Ostrowski root-seeking method which I consider a gem of an algorithm that has not received much publicity until somewhat recently. I also present listings for Ostrowski’s method to run on the WP34S calculator (using a repurposed HP 30b) and on the new HP 39gII. Before I discuss the algorithm and present the two listings, I would like to first shed some light on the person of Ostrowski. Ostrowski: A Short Biography Alexander Markowich Ostrowski (1893 to 1986) was a talented Russian mathematician who was gifted with a phenomenal memory. He was studying math at Marburg University in Germany, when World War I broke out.

  • Measuring Calculator Current – Nine Measurement Examples Richard J
    Measuring Calculator Current – Nine Measurement Examples Richard J. Nelson Introduction In HP Solve, issue #28 page 30, I described the importance and problems of measuring the current that a calculator draws from its “battery(1).” In that article I gave an example of the HP-41 and the current it draws under a very few selected conditions. I also described how the current a calculator draws frequently changes, often quite rapidly and drastically, depending on what the calculator is doing. Low power consumption is essential Nearly every reader has an extremely complex battery operated device such as a cell phone, game device, tablet, etc. Since we use these battery operated devices every day the need for drawing a minimum amount of current is a critical aspect of their design. Using the lowest possible power is the mantra for every circuit designer for battery operated products these days. What is amazing is the fact that since the digital circuits are able to operate so fast, and the sloth like human operators are so slow, that the circuit may be turned “off” and back on again while the human “decides” what to do, or how to deal with the previous result. Modern circuit design utilizes this current shut down concept in as many situations as possible throughout the complex circuitry. One of the reasons to measure the current draw – in addition to troubleshooting – is to be able to estimate the battery life of the machine. In terms of doing this you have to be careful, however, because of the many possible operating conditions, and that they may change faster than your meter can respond.
