# Command Line Calculator

## Publisher's Description

The main features of the program are:

Expression calculation, unlimited length Plotting graphs Variables can be used User can define own functions Saving and opening previous calculations Temporary file and history list Date calculation Following numbers are supported: decimal, hex, octal and binary Bitwise operations are supported Several statistics calculations Over 70 in build functions available

Expression calculation There is no limit to the length of expression, which can be entered into calculation. Program supports variables and most of the typical functions like trigonometric functions, logarithms, basic operations and so on, see more details from the help page.

Plotting graphs One can also do one variable plots with plot command. In the picture is shown functions "sin(x)/x", "sin(1.2*x)/x" and "sin(1.4*x)/x". User can zoom and pan the plot with mouse's left and right button and with double click - see picture on right. All calculations are stored into history list, from where one get them by pressing space bar.

Variables One can set variables. For example writing w=98, sets w's value to 98. Variables can then be used later in calculations. For example w+3 would give 101. There is also separate window for variables, which can be used together with main window. See under menu item "View".

User defined functions User can set his or hers functions. For example f(x)=x+2*sin(x). See picture on right for more details. User can set multi variable functions. User can also call earlier defined functions in the later functions. For example in the picture on right one can see that function "y" is used also in the function "g".

Opening and saving calculations User can save his or hers strings into a file and use them later.
