*DaTI-Online is best in browser mode.

DaTI is a calculator I made out of JavaScript. The original link is here. If the link for the terminal doesn't work, just go to my profile and click on DaTI.

It includes:

Addition
Subtraction
Multiplication
Division
Exponents
Diameter
Absolute Value
Radius
Circumference
Perimeter [S]*
Perimeter [R]*
Area [S]
Area [R]
Area [C]*
Functions (Only basic multiplication)

* [S] = Square, [R] = Rectangle, [C] = Circle

Future plans

I might add y=mx+b, also known as slope-intercept form, and other geometric conversions. Otherwise, I'm happy with it. ^^

Enjoy!
