Where i can get reference for making a scientific calculator?

Because there so many sample to make a simple calc. i wonder is there any reference so i can get understand to create a scientific calc. Is it possible to do?

Thank You All.. :)

That depends on how deep you want to go, the high level is just to use the Math object in JavaScript. Click to view the documentation reference.

So i can attach javascript function on my project? or is somekind of already internally build function without adding more addons?

Yeah, using the built-in Scripting feature.

ok, i 'll try, thanks
