Maxcalc

Today i am demonstrating my own calculator.

I created that calculator using Visual Basic 6.0 because I wanted a portable lightweight application. Indeed it can run natively from Windows 95 until now, without having to update or install anything else.

It is small and always on top so that I can always have access to it while doing my other tasks.

The syntax is Matlab like, but it is not as picky so you can type equation in a hurry. For examples:

1-You don’t have to close the braces. (Typing: “2*(1+1” is equivalent to “2*(1+1)”)

2-It evaluate as you type so you can correct in real time. (No waste of time by pressing “Enter” for every equation)

3-It assumes a default value that makes sense when a value is missing for most equation. (“1+” is the same as “1+0”, but “1*” is the same as “1*1”. So if you start a long sequence of sum or multiplication it won’t bother you with trailing operator.)

4-It is a normally a one liner, although more complex equation can be performed while recalling previous equations using the Max’s special character $ and #.

I have many features such as:

1-Arrays (limited to 1 dimension in the syntax) (Example: ”(1,2,3)^2 = 1,4,9” which is handy for repetitive calculation. Furthermore a simple F7 key press show those value on a graph.

2-Support FFTs

3-Support Images, wav, txt files

4-Support Clipboard

5-Support Command line

6-Can perform animations for an extra dimension J

7-Support Sound Card access (Although limited in performance)

8-Support visual studio like F2 key to list commands that match actual beginning of equation.

Example of more complex possibility:

The following equations animate a frequency and its associate spectrum:

"loop(0.1,1:5);64;sin($1*(1:$2)/$2*2*pi);plot($3);plot(norm(hfft($3"

Multiple small equations are involved here. There is the break-out to understand:

loop(0.1,1:5);

Perform a loop at maximum speed for value 1 to 5

64;

A constant

sin($1*(1:$2)/$2*2*pi);

Calculate a time signal. ($ recall previous outputs separated by ;)

plot($3);

Plot previous time signal created

plot(norm(hfft($3

Plot the magnitude of the fft of the time signal previously generated.

If you are interested in the application I have started a source forge project at: https://sourceforge.net/projects/maxcalc/

Feel free to give it a try! Its free and it will always be. And don't worry, the complete used guide is given for all equations and their synthax.
