Version 1.5, added JavaCalc LITE as a light weight popup window but no Help.
Add unlimited Undo and Redo button. You can recall any historical input in
the session. A box under the Redo indicates the history page number. findroot
now accepts to enter equation balanced by "==".
Version 1.4, added findroot for finding a root of equation in one variable.
Try findroot( "x*x-2", 1), findroot( "x-sin(x)", 1)
Try ?FORM, ?sin
Version 1.2, supports extended factorial that means non-integer n, the numerical
value of factorial(n) is given by gamma(1 + n). Thus it has now gamma function
and handle negative numbers as well.
Try factorial(3.45), factorial(-1.23), factorial(-10).
by Netscape). You can evaluate your expressions in the above INPUT box.
own functions, loops and other statements on the JavaCalc. Not necessary to
write the code in HTML format and open it by Browser. I have been developing
on major browsers. JavaCalc may have limitation to use as Interpreter.
However, I believe, you can still enjoy its powerful functions, variables and
Note 1) Variable and function names are caps sensitive.
Note 2) Some enhanced script commands are not compatible between Netscape and Internet Explorer.
Note 3) Keyword compatible does not mean runtime compatible. You should test
both environment. For example, Netscape try to keep definition through the
session but IE does not. Netscape Communicator 4.7 seems more buggy than IE5.0.
One difference is that JavaCalc allows to use mathematics function without
typing "Math" method. For example, you can type sin(0.5) as a short-cut
instead of Math.sin(0.5).
In addition, actually you don't need to connect to my home page every time.
Because, it uses Netscape 2 and later built-in functions. Click here
and saves the page through the Netscape menu View/Document Source. When you
need the JavaCalc off-line, drop the saved source onto Netscape. You can use
to FRAME mode.
JavaCalc can do more than calculator. Enjoy, Ken
