Description. Feature rich software scientific calculator for PC with advanced support of complex algebra.
FeaturesScientific calculator LiXc is our software expression calculator for making advanced complex algebra — besides traditional Librow calculators functionality this piece of software provides total support for complex numbers and has advanced function set, which includes gamma, ordinary Bessel and modified Bessel functions of the complex argument:
1. Easy to learnLiXc calculator is expression calculator, which means it can evaluate the whole expression at once. To evaluate expressions in LiXc calculator or program it you are to know book notation, eastern or western, or notation, traditional for PC programming, and a couple of keywords. Here they are: Memory (Mem) and Result (Rslt). Use access to current result like:
Store values to memory like:
Use the value in memory like (short notation):
2. ProgrammableIf your calculations are long, sophisticated and multistaged — scientific calculator LiXc can manage that for you. Enter all your formulas, use memory for storing results and utilizing them in other formulas, evaluate single formula or all of them at once, run your calculations as script. Here is a primitive script sample, which calculates phase, sets time and evaluates expression as function of phase and time:
Case study. Download script samples
and read this case to study how scripts can help you to organize your calculations. 3. Integrated text processorEnter your formulas from keyboard, edit them, insert comments. Your edit window area is limited only by display of your PC. Change the text editor font to your likeness. 4. Statistics supportCalculate mean, variance, standard and average deviations, skewness and kurtosis in one click — put the input data into memory and click St button to evaluate all parameters. Fig. 2. Statistics window.5. File supportSave your work to disk. LiXc calculator files have text format, so, you can edit and create calculations in any text editor and then load into calculator for evaluation. Run your calculation scripts without loading them into the editor. 6. Print supportYou can print your calculations, control how they appear on paper, add header and footer to every page with file data, date, time and page number, set proper margins and preferable fonts. Fig. 3. Page setup dialog.7. Smart keypadYou can hide keypad to maximize display area and work only from PC keyboard. Or you can detach and place it at any comfortable position. Change color, size and appearance to your likeness. Change its notation and set preferences to automatically append functions with opening parenthesis. Fig. 4. Detached Keypad in custom colors.8. Extended memory controlYou can allocate as many memory cells for intermediate results as you need, just provide unique names for them. You can save memory to disk to use results in other calculations. Fig. 5. Memory window.9. Advanced complex numbers supportScientific calculator LiXc was developed for making complex algebra and supports all trigonometric and hyperbolic functions of the complex argument along with their inverses. As advanced features the calculator supports complex versions of:
Among other advanced features: 10. Context helpGetting help for any item you can see in LiXc calculator is as easy as two clicks — just click the question mark button in toolbar and then click the item of interest — and you will be taken to the page with explanation. Fig. 6. LiXc calculator Help.11. Embedded function handbookAs its part LiXc calculator help has function handbook, which contains all function definitions, graphs and identities. To access the handbook click the question mark button in toolbar and then click the corresponding function button in keypad — and you will be taken to the handbook function page like “arcsin — trigonometric arc sine function”.
