cos(pi/4 is automatically corrected to cos(pi/4).Qalculate! - the ultimate desktop calculator Speaking about parentheses, closing them can be left to SpeedCrunch, e.g. For example, just typing sin followed by Enter - likely means taking the sine of last value - is automatically translated as sin(ans).Īlso, for some functions you may skip the parentheses if you pass simple number or variable, sin 0.1 is as valid as sin(0.1). Often, SpeedCrunch can still understand an incomplete expression. This means you can still invoke those calculations you have done yesterday or last week. Moreover, your expression history (maximum last 100 expressions) is saved between sessions. If you want to recall again the expression which you typed before, then press up and down arrow to access the expression history. When your calculation is quite complex and involving a chain of operations, this high precision ensures that you would get less rounding error in the end. Normally all the important digits are shown, but you can also ask SpeedCrunch to round it to several digits only. Precision With its unique calculation routines, you can get up to 50 decimals of precision. Type the letter c only and in less than a second you will be automagically given with choices of cos, cosh or your variables whose name start with c. Or take advantage of its auto-completion. 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. Simply customize the colors (from the Settings menu) if the default don't please you.Īutocomplete Beside standard algebraic operator like + (addition), - (subtraction), * (multiplication), / (division), ^ or ** (exponentiation), there is support for some functions, for example sin, log, abs, and many more. You can also see the matched parentheses. You can easily distinguish numbers from variables. Highlight Do you close your parentheses correctly? Mistype the number? No need to worry again because SpeedCrunch can always color the expression according to the syntax. 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. And still, you can define as many variables as you want. Variables need not only a character, InterestRate is a perfect name as well. SpeedCrunch allows variables to hold calculation result, e.g. This allows you to "fix" your expression if you think it is not what you want.Īdvanced calculation sometimes needs memory feature. And, you can quickly copy the last calculation result to the clipboard using Ctrl+R.Īutocalc Before you finish, SpeedCrunch may even give already the answer (calc-as-you-type, anyone?). You can also paste the expression from the clipboard, that you copied from somewhere else.
That is faster and more convenient, isn't it? You can see clearly what you typed along with the result in the scrollable display. You just type the expression that you want to calculate and press Enter. Unlike traditional desktop calculator, SpeedCrunch is easier to use.
