What is java scientific calculator?
Java Scientific Calculator is a general-purpose scientific calculator that you can use as a computer-desktop calculator or in a web application. In addition to basic arithmetic functions it provides trigonometric functions, logarithms, powers and roots, complex numbers, binary, octal, decimal and hexadecimal calculations, logic, scientific notation, memory, statistical funcions (mean, and population and sample standard deviations), permutations and combinations. It also supports editing and replay of input and copying of output to the (system) clipboard. You can resize the application to one of three sizes and use the keyboard instead of the mouse for all keys.

System requirements
  • Minimum JRE: 1.6.0

java scientific calculator on an eComStation machine with Open JDK

Installing java scientific calculator
Download jscicalc2-0.5.jar. Make a directory/map with the name "scalc". Copy the file "jscicalc2-0.5.jar" to the new created directory/map. That's it!

The used cmd file
Java scientific calculator works with Open JDK in OS/2-eCS. I have a "scalc.cmd" file with the following contents;
@echo off
set BEGINLIBPATH=[drive: java]\JAVA160ga5\bin
set path=[drive: java]\JAVA160ga5\bin
[drive: scalc]
cd [drive: scalc]\scalc
java -jar jscicalc2-0.5.jar 2>jscicalc2-bugs.txt 
I use 2 separate folders (directories), one for Java and one for Java scientific calculator. The references used in the cmd file;

  • [drive: java] = drive with Java
  • [drive: scalc] = drive with java scientific calculator

should be replaced with real drive letters. Save the file and name it "scalc.cmd" or use the file from the distribution. This file is copied to the "scalc" folder (directory). Furthermore, different paths?, adjust according to your needs.
Create a new program object. Specify the path and file name: "[drive: scalc]\scalc\scalc.cmd". In the tabpage Session check the boxes "OS/2 window", "Running as an icon" and "Close Window to end program". In the tabpage General you can enter the name "java scientific calculator".

Parameters / options explained
  • The addition "2>jscicalc2-bugs.txt" ensures that errors are saved in the file "jscicalc2-bugs.txt". The 2 in "2>" is not a typo! The files stays empty on my system.

In the file you can find the above command files (all drive letters are on set to C:) and an OS/2 java scientific calculator icon: scalc-ecs.zip.
