Command Line Calculator is general purpose calculator. Calculations are entered on command line and result is produced after pressing enter - see picture on right of typical calculations.
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.
Temporary file and history list
Date calculation
Bitwise operations
Statistics calculations
What is new in this release:
2013 August version 3.1 - New version of math core. - New development environment, so that newer operating systems can be supported - User can now set either comma ',' or dot '.' as decimal separator. When user sets for comma as decimal separator then argument separator is semicolumn. When user sets dot as decimal separator then argument separator is comma. - Division by zero creates Inf instead of "Division by zero message". If answer is Inf, program stores this to history list but not into variable - log, log2 and log10 are discontinued. New function log(base,num) replaces these. Now log(e,x) is same than log(x) was, log(2,x) is same than log2(x) was and log(10,x) is same than log10(x) was. In addition you can now make what ever logarithm functions with what ever base number you would like to. - exp, exp2 and exp10 are discontinue, just use normal power operator "^", for example exp(x) cam be calculated now e^x. - New function "floor" added, see help details - New function "roundto" added, see help details - Function frac gave wrong answer with negative numbers, this has been fixed - Following hyperbolic functions returned always radians independent of angle setting: asinh, acosh, atanh, acoth asech and acsch. Now all these funtions returns angle according to set angle. - When changing setting of "Stay on Top" or setting "decimal separator", program gives message box that program needs to be restarted to make these changes effective. - Plotting of functions renewed: one can set for each plot now color and line thickness. Also title, xlabel and ylabel can be set. on can also print the plot. - Using Ctrl and mouse's middle roll will now zoom font size - New random generator, see help "in build functions" more - Styles add. There are 8 different styles now available in the settings page. - In Statistics window was error, if user put floating point values as input, then sometimes program removed decimal part from a number in the Sorted window. This has been fixed. - Natural constants added as a separate window. User can more natural constant to main window just by clicking it.
