Sorry, but your calculator have a bug (is there a intel inside?)

Try to calc 80.57 - 50 = ?

.... and you get 30.5699999

Sorry, but a calculator what can't do right calculations is totally useless.

Great calculator Todd. Is it possible for you to create a 'graphics calulator' widget (or do you know of an existing one?). Thanks for your help.

There is a problem with this widget when using the keyboard. Try .123 - .045 using your keyboard.
I really like the history file option.
How about allowing us to change its color?

There are some instructions in a txt file in the zip file you downloaded. I couldn't find it there but reading the version history at the top of this page, you can find out this: "copy/paste buttons in lower-left conrner of display".

Try writing a number, klick at the "left arrow" and then writing another number and klick at the "right arrow".

Then the first number should be pasted into the writing area of the display.

I really like the Calc widget, but where are the instructions? At least can somebody tell me what the little buttons do that have a left arrow pointing at a "document" and the right-arrow pointing at a "document".
