EditCalc è costruito intorno ad una finestra in cui è possibile inserire espressioni matematiche. Il programma supporta gli operatori standard e le funzioni fondamentali, trova le radici, gli integrali e calcola alcune statistiche.
Il programma è distribuito come pacchetto ZIP: scaricare in una cartella temporanea e scompattare nella cartella di destinazione. Vedi sotto per il(i) link di download.
Qui di seguito trovi i link di download per l'installazione manuale del software:
EditCalc v. 0.1a (5/1/1997, Frank Carlsson) | Readme/What's new |
Readme file for EditCalc version 0.1a (Freeware) Jan-97
WHAT'S NEW SINCE Sep-95?
Hardly anything. The important thing is that I've removed the expire date
which should make at least one person in this universe happy.
DISCLAIMER:
I allow you to use and distribute EditCalc.exe and the files listed below
freely under the condition that I am in no way responsible for any damages
or losses you may suffer as a result on copying, installing or using
EditCalc.exe and its accompanying files.
WHAT DOES IT DO?
EditCalc is build around an edit window in which you can enter mathematical
expressions. An example is: 5*log(10+2).
To solve this simple expression keep your text cursor at the same line were
you have the mathematical expression and click the tool bar button or
select the menu option, or, if you've got good (brain)memory, use the
accelerator keys. The result in any way will be: 5*log(10+2) =
5.39590623023812.
More complex operation can be used including integration and the solving of
ordinary differential equations. However remember that the only allowed
variables are x, y1, y2, ..., yn. Were x is the independent variable and
y1, y2, ...yn are the dependent variables, were n is the number of
equations under operation at the same time.
WHAT'S MIGHT BE IN STORE FOR THE FUTURE?
At this point the mathematical routines are not especially sophisticated.
Runge-Kutta (solving ODE), Secant method (Root find) and Simpsons formula
(Integration) are methods found in any basic numerical book and in any
basic course of numerical procedures. Perhaps the routines are old and new
routines should be used? I welcome help from anyone in finding better
routines in C/C++ that can be used freely and have minor changes effected
in need be. However, what is much more important is correcting serious
bugs. So please report, as soon as possible, any bugs you find and when
they occur.
I can't promise that I will implement better routines and I can't even
promise that I will correct serious bugs. It depends on a lot of factors,
including the personal time I have available to work on this program
FILES INCLUDED AND CREATED:
EditCalc.exe - The executable program.
EC.hlp - Help file used by EditCalc.exe (it is required).
EditCalc.ini - A file created the first time when the program terminates. Contains setup information.
LastSess - A text file created when closing the program. It contains the text present in edit window.
ReadMe.txt - This file
SYSTEM REQUIREMENTS:
To be able to run this you need WARP OS/2 3.0 or later.
WHICH COMPILER HAS BEEN USED?
I've written this in VisualAge C++ (IBM) using the included Open Class Library.
Which should make the program rather portable. That might be of interest if
I realease the source code.
BUG REPORTS, SUGGESTIONS AND OPINIONS:
Please send any bug reports or suggestions to my E-mail account frank.carlssonk@stockholm.mail.telia.com.
I'm also interested in what people think about this user interface. So tell me about it!
It's also allowed to correct my poor English, especially in the help text.
I hope you find a use for this program!
