Your expression history (maximum last 100 expressions), as well as variables you have defined, are saved between sessions. Another variable pi holds one of the most important constant in math world. There is a special variable, ans, which always holds the last calculation result. When you want to use a variable but you can not recall its exact name, use Ctrl+I to show a list of variables that you can pick easily. You can define as many variables as you want. Using assignment, such as x=0.3 means that variable named x has the value of 0.3, which you can always later on, for example sin(x). SpeedCrunch allows variables to hold calculation result. Or take advantage of auto-completion feature, for example type the letter s only and in less than a second you will be automagically given with choices of sin, sinh or sqrt.Īdvanced calculation sometimes needs memory feature. You do not need to memorize function names, use Ctrl+F to pop up a dialog where you can choose the function that you need. If you want to reuse again the expression which you typed before, then press up and down arrow to access the expression history.īeside standard algebraic operator like + (addition), - (substraction), * (multiplication), * (division), ^ or ** (power), there is support for some functions, for example sin, log, abs, and many more. And, you can quickly copy the last calculation result to the clipboard using Ctrl+R. Result is shown in the scrollable display. SpeedCrunch is easy to use, just type the expression that you want to calculate and press Enter. Result is shown in scrollable window, history of expressions is available with up and down arrow. SpeedCrunch is designed to be enjoyed using keyboard. It has a compartment for 4 AAA batteries, but can run with only 1 AAA fitted.SpeedCrunch is a fast, compact, high-precision calculator (up to 50 decimal digits), ideal for power users. This calculator has a peculiarity I've never seen in any other battery powered device (excuse my lack of knowledge if that's the case).
HP 39G II (not in the photo) was a bit of a surprise. Hence the difference in the results from the 4th decimal digit. It has a compartment for 4 AAA batteries, but can run with only 1 AAA fitted. HP19B II, HP10S, HP39G II, Casio FX-350ES plus, Casio FX-82MS, Casio FX-991SPX, Casio FX-82SPX, Casio FX-570SPX Out of curiosity, one of this days run a test on some calculators at home Integral of ln(x^2)dx, from -5 to 99 (EDIT: as can be seen in the photo, on Casio FX-991ES display) Casio FX-991ES - 3m15s - 717.9281095 HP 39G II - 7s - 717.928109451 HP 49G+ - 25m 38s - 717.928325369 HP 40GS - 20m48s - 717.928325369 HP 49G - 54m54s - 717.928325369 HP 48G - was not able to solve Microsoft Mathematics on a i5 - 0s - 717.9281094509898 When applicable, HP 40GS, 49G and 49G+ had to be configured for complex and approximation mode, otherwise they couldn't solve. I have a few more at home, from wife and kids. Gathered all my current calculators for a photo family. I have a lot more calculator options than brains.
#Speedcrunch list windows#
I may use the windows calculator on occasion, Excel or Microsoft Mathematics and once in a wile some online dedicated calculator for things like filters, 555, LM317.
#Speedcrunch list install#
Even though, I install in all my computers, some of the free HP calculator emulators, it's not very practical to keep mouse clicking on the calculator buttons. in some cases a calculator, is such of those things. Assorted screwdrivers, pliers, multimeter. Between home, car and work, I hate to have to go back to get something I need and forgot, so I have duplicates (triplicates.) of some tools I usually need. I live in the 2nd floor of a building, have a garage and an attic. As with other tools, I tend to collect calculators and then scatter them all over.
