A calculator which allows evaluation of JavaScript expressions as well as the usual. You can use the keys or type directly into the calculator. The left and right arrow keys can be used to move the cursor when editing the expression.
Because it can run any JavaScript it's probably not safe to run on a website. Running from the Dashboard is fine however.
Functions supplied include: sin(x), cos(x), tan(x), asin(x), acos(x), atan(x), abs(x), log(x), sqrt(x), cbrt(x), base(x,y), pow(x,y), utf8(x) plus PI() and E()
Easy to extend - no images! Just edit the HTML to add buttons.
