Math & Science - Evaluate

Description: Evaluate is a Dashboard widget that uses the Javascript 'eval' function to process text entered into an input line. The results are output to a buffer so that you can view/copy results from previous calculations. Since the widget uses the eval function to process input you can use the widget to evaluate any valid javascript and even store variables.

Beautiful Design! Great widget, i do think at some point it should parse words such as times divided by plus but it doesn't need to. I love it.

Thanks for your comments, Bryan. That's an interesting suggestion that's fairly easy to implement. I also plan on adding support for implicit multiplication in the next version so that you can do things like 3pi (as opposed to 3*pi).

This is great, but there's something funny about floating point values. When I add 0.2+0.1, I get 0.30000000000000004, and when I multiply 0.3*3, I get 0.8999999999999999.

This seems to happen a lot with floating point values with only one decimal point.

Another helpfull feature would be:

example:
if this is you recent calculation:
542*546
=295932
and you now want to continue by adding 567 to the result.
It would be nice if you just had to type:
"+567" instead of "295932+567"

Just how the common calcs do it!

-> if formula starts with operator (+-*/) then instert last result at the beginning of the new formula.

BTW: As I did the Design I didn't rate for it smiley

@ Bryan: Thanx for your kind words! Feedback is always appreciated!

Great design. I can't figure out what ^ is supposed to do. Could you make it a^b=pow(a,b) for ease of typing?
