Speedcrunch examples free#
The best alternative is SpeedCrunch, which is both free and Open Source. Here are some key features of "SpeedCrunch": There are more than 50 alternatives to SpeQ Mathematics for a variety of platforms, including Windows, Android, Mac, Online / Web-based and iPhone. cos(pi/4 is automatically corrected to cos(pi/4).įor your convenience, it is even possible to customize the font and color used for the display. Speaking about parentheses, closing them can be left to SpeedCrunch, e.g.
Also, for such function you may skip the parentheses if you pass simple number or variable, sin 0.1 is as valid as sin(0.1). For example, just typing sin followed by Enter - likely means taking the sine of last value - is automatically translated as sin(ans). Example: '50 usd in gbp', '100usd in (x in gbp)' and so on. Up until now I was using Numi, but I felt like it's time to move on to Linux and over there nothing compares to speedcrunch. Often, SpeedCrunch can still understand an incomplete expression. I really, really appreciate this project and currency support would be beneficial for all of us.
This means, you can still recall those calculations you have done yesterday or last week. 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. SpeedCrunch is a fast, compact, high-precision calculator (up to 50 decimal digits), ideal for power users.
