Find attached a public beta java-script-calculator port for the PRS-505.
Attention: There is a bug in the released code!
Parenthesis "(" ")" arn't working. Giving (1+2)*3=7 which is obviously wrong.
Solution: rename
var openp = function(){ to var popen = function(){
and
var closep = function(){ to var pclose = function(){
in "calculator.js"
Valid code is integrated in PRS+ here
I just add this information here and want not to push this article by a new posting to this thread.
Use and start it like any other Autorun-App.
UserInterface is pretty straight forward:
Move pointer with "joystick", select key/function with "center"
Nummeric buttons can be used to input numbers too.
NextPage and holding center button = equals
PreviousPage "C"lear last input
Menu-Button exits the app.
Basically this is a port from:
http://www.motionnet.com/calculator/
Changes are done in "sign", "M+", intruduced "M-" and "%" as well as a "C"lear besides the "AllClear"-Button
This app was developed most of the time in my "
FSK Test-Environment for Autorun Applications under MS-Windows"
