Calculator with virtual paper roll V.2.0
Even if this is mainly a hobbies site I am offering here a tool that might increase your
personal productivity for home and office work.
Using it you might save some time to spend on more amusing things, including other
games and entertainments put in my site.
On Internet you can find a lot of sites offering calculators, even very sophisticated.
But the one I am offering here has the following features:
it is free,
it can be used on line or downloaded to your PC to work unconnected,
it joins its keyboard with a “virtual paper roll” to record all data and operations you
make (an important feature to work surely and avoid mistakes).
1 - current operation
2 - current result
3 - next operation
4 - sign change
5 - decimal point
6 - cancel last digit
7 - clear current calculus
8 - clear calculus and paper roll
9 - clear memory
10- add or subtract to memory
11- memory recall
12- current memory value
13- rolling tape showing operations and results
14- decimal digit number (with rounding)
The Calk'n'Roll can be downloaded from here.
The CALKNROLL20.zip file, when un-zipped, shows the
CalknRoll20.hta program and the CalknRoll.ico
icon that must be kept in the same folder.
- the application works in browser independent mode and shows its specific icon on the
- accepts '+ - * /' numeric pad keys, if available, like the
'+ - x :' Calculator buttons;
- accepts the keyboard Enter key like the '=' Calculator button;
- accepts the keyboard Canc/Del key like the 'C' Calculator button.
Have a fine work!
